Animator

An animator is one who is involved in the process of animation. How this person actually creates animation depends on the field in which he or she works. Some fields in which an animator may work:
- Motion pictures
- Television
- Video games
- The Internet Among the specialized categorizations of animators are character animators (artists who specialize in character movement, dialogue, acting, etc.) and special effects animators (who animate anything that is not a character; most commonly vehicles, machinery, and natural phenomena such as rain, snow, and water).

This animation moves at 2 frames per second. At this rate, the individual frames should be discernible.

Animation is the illusion of motion created by the consecutive display of images of static elements. In film and video production, this refers to techniques by which each frame of a film or movie is produced individually. These frames may be generated by computers, or by photographing a drawn or painted image, or by repeatedly making small changes to a model unit (see claymation and stop motion), and then photographing the result with a special animation camera. When the frames are strung together and the resulting film is viewed, there is an illusion of continuous movement due to the phenomenon known as persistence of vision. Generating such a film tends to be very labour intensive and tedious, though the development of computer animation has greatly sped up the process. Graphics file formats like GIF, MNG, SVG and Flash allow animation to be viewed on a computer or over the Internet.

History

For a more in-depth look at the history of animation, please see the Wikipedia articles "Animated cartoon" and "History of Animation". The major use of animation has always been for entertainment. However, there is growing use of instructional animation and educational animation to support explanation and learning. The "classic" form of animation, the "animated cartoon", as developed in the early 1900s and refined by Walt Disney and others, requires up to 24 distinct drawings for one second of animation. This technique is described in detail in the article Traditional animation. Because animation is very time-consuming and often very expensive to produce, the majority of animation for TV and movies comes from professional animation studios. However, the field of independent animation has existed at least since the 1950s, with animation being produced by independent studios (and sometimes by a single person). Several independent animation producers have gone on to enter the professional animation industry. Limited animation is a way of increasing production and decreasing costs of animation by using "short cuts" in the animation process. This method was pioneered by UPA and popularized (some say exploited) by Hanna-Barbera, and adapted by other studios as cartoons moved from movie theaters to television. television

Animation studios

Animation Studios, like Movie Studios may be production facilities, or financial entities. In some cases, especially in Anime they have things in common with artists studios where a Master or group of talented individuals oversee the work of lesser artists and crafts persons in realising their vision.

Television

: Television is a telecommunication system for broadcasting and receiving moving pictures and sound over a distance. The term has come to refer to all the aspects of television programming and transmission as well. programming ]]

History

The development of television technology can be partitioned along two lines: those developments that depended upon both mechanical and electronic principles, and those which are purely electronic. From the latter descended all modern televisions, but these would not have been possible without discoveries and insights from the mechanical systems. The word television is a hybrid word, created from both Greek and Latin. Tele- is Greek for "far", while -vision is from the Latin visio, meaning "vision" or "sight". It is often abbreviated as TV or the telly.

Electromechanical television

The German student Paul Gottlieb Nipkow proposed and patented the first electromechanical television system in 1885. Nipkow's spinning disk design is credited with being the first television image rasterizer. However, it wasn't until 1907 that developments in amplification tube technology made the design practical. Meanwhile, Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on August 25, 1900. Perskeyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others. 1900 In 1911, Boris Rosing and his student Vladimir Kosma Zworykin achieved a television system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the electronic Braun tube (cathode ray tube) in the receiver. Moving images were not possible because, in the scanner, "the sensitivity was not enough and the selenium cell was very laggy." Zworykin later went to work for RCA to build a purely electronic television, the design of which was eventually found to violate patents by Philo Taylor Farnsworth. On March 25, 1925, Scottish inventor John Logie Baird gave a demonstration of televised silhouette images at Selfridge's Department Store in London. But if television is defined as the transmission of live, moving, half-tone (grayscale) images, and not silhouette or still images, Baird achieved this privately on October 2, 1925, and gave the world's first public demonstration of a working television system to members of the Royal Institution and a newspaper reporter on January 26, 1926 at his laboratory in London. Unlike later electronic systems with several hundred lines of resolution, Baird's vertically scanned image, using a scanning disc embedded with a double spiral of lenses, had only 30 lines, just enough to reproduce a recognizable human face. In 1928 Baird's company (Baird Television Development Company / Cinema Television) broadcast the first transatlantic television signal, between London and New York, and the first shore to ship transmission. He also demonstrated an electromechanical colour, infrared (dubbed "Noctovision"), and stereoscopic television, using additional lenses, disks and filters. In parallel he developed a video disk recording system dubbed "Phonovision"; a number of the Phonovision[http://www.tvdawn.com/tvimage.htm] recordings, dating back to 1927, still exist. In 1929 he became involved in the first experimental electromechanical television service in Germany. In 1931 he made the first live transmission, of the Epsom Derby. In 1932 he demonstrated ultra-short wave television. Baird's electromechanical system reached a peak of 240 lines of resolution on BBC television broadcasts in 1936, before being discontinued in favor of a 405 line all-electronic system. In the U.S., Charles Francis Jenkins was able to demonstrate on June 13, 1925, the transmission of the silhouette image of a toy windmill in motion from a naval radio station to his laboratory in Washington, using a lensed disc scanner with 48 lines per picture, 16 pictures per second. AT&T's Bell Telephone Laboratories transmitted half-tone images of transparencies in May 1925. But Bell Labs gave the most dramatic demonstration of television yet on April 7, 1927, when it field tested reflected-light television systems using small-scale (2 by 2.5 inches) and large-scale (24 by 30 inches) viewing screens over a wire link from Washington to New York City, and over-the-air broadcast from Whippany, New Jersey. The subjects, which included Secretary of Commerce Herbert Hoover, were illuminated by a flying spot beam and scanned by a 50-aperture disc at 16 pictures per second.

Electronic television

Herbert Hoover Although the discoveries of Nipkow, Rosing, Baird and others were extraordinary, little of their technology is used in modern television. By 1934, all electromechanical television systems were outmoded, although electromechanical broadcasts continued on some stations until 1939. A.A. Campbell-Swinton wrote a letter to Nature on the 18 June 1908 describing his concept of electronic television using the cathode ray tube, which had been invented in 1897 by the German physicist and Nobel prize winner Karl Ferdinand Braun. He proposed using an electron beam in both the camera and the receiver, which could be steered electronically to produce moving pictures. He lectured on the subject in 1911 and displayed circuit diagrams, but no one, including Swinton, knew how to realize the design. Although his system was never built, the cathode ray tube did come to be used to display images in almost all television sets and computer monitors until the invention of the LCD panel. A fully electronic system was first achieved by Philo Taylor Farnsworth on September 7, 1927, although the low-resolution, light-insensitive camera tube limited the image to a plate of glass painted black, with a straight line etched across it, rotated in front of a bright carbon arc lamp. Seven years later, on August 25, 1934, at the Franklin Institute in Philadelphia, Farnsworth gave the world's first public demonstration of a working, all-electronic television system, with 220 lines per picture, 30 pictures per second. Over a three week period, vaudeville acts, athletic and sports demonstrations, politicians, and hundreds of ordinary citizens were captured on Farnsworth's cameras in the open air and simultaneously shown on his receiving sets. Farnsworth, a Mormon farm boy from Rigby, Idaho, first envisioned his system at age 14. He discussed the idea with his high school chemistry teacher, who could think of no reason why it would not work (Farnsworth would later credit this teacher, Justin Tolman, as providing key insights into his invention). He continued to pursue the idea at Brigham Young Academy (now Brigham Young University). At age 21, he demonstrated a working system at his own laboratory in San Francisco. His breakthrough freed television from reliance on spinning discs and other mechanical parts. All modern picture tube televisions descend directly from his design. Vladimir Kosma Zworykin is also sometimes cited as the father of electronic television because of his invention of the iconoscope in 1923 and his invention of the kinescope in 1929. His design was one of the first to demonstrate a television system with all the features of modern picture tubes. His previous work with Rosing on electromechanical television gave him key insights into how to produce such a system, but his (and RCA's) claim to being its original inventor was largely invalidated by three facts: a) Zworykin's 1923 patent presented an incomplete design, incapable of working in its given form (it was not until 1933 that Zworykin achieved a working implementation), b) the 1923 patent application was not granted until 1938, and not until it had been seriously revised, and c) courts eventually found that RCA was in violation of the television design patented by Philo Taylor Farnsworth, whose lab Zworykin had visited while working on his designs for RCA. The controversy over whether it was first Farnsworth or Zworykin who invented modern television is still hotly debated today. Some of this debate stems from the fact that while Farnsworth appears to have gotten there first as an inventor, RCA brought television sets to market before Farnsworth, and it was RCA employees who first wrote the history of television. Even though Farnsworth eventually won the legal battle over this issue, he was never able to fully capitalize financially on his invention.

Color television

Most television researchers appreciated the value of color image transmission, with an early patent application in Russia in 1889 for a mechanically-scanned color system showing how early the importance of color was realized. John Logie Baird demonstrated the world's first color transmission on July 3, 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color; and three light sources at the receiving end, with a commutator to alternate their illumination. Color television in the United States had a protracted history due to conflicting technical systems vying for approval by the Federal Communications Commission for commercial use. Mechanically scanned color television was demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells, amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full color image. In the electronically scanned era, the first color television demonstration was on February 5, 1940, when RCA privately showed to members of the FCC at the RCA plant in Camden, New Jersey, a television receiver producing images in color by a field sequential color system. CBS began non-broadcast color experiments using film as early as August 28, 1940, and live cameras by November 12. The CBS "field sequential" color system was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1,200 rpm, and a similar disc spinning in synchronization in front of the cathode ray tube inside the receiver set. RCA's later "dot sequential" color system had no moving parts, using a series of dichroic mirrors to separate and direct red, green, and blue light from the subject through three separate lenses into three scanning tubes, and electronic switching that allowed the tubes to send their signals in rotation, dot by dot. These signals were sorted by a second switching device in the receiver set and sent to red, green, and blue picture tubes, and combined by a second set of dichroic mirrors into a full color image. The first field test (i.e., broadcast) of color television was by NBC (owned by RCA) on February 20, 1941. CBS began daily color field tests on June 1, 1941. These color systems were not compatible with existing black and white television sets, and as no color television sets were available to the public at this time, viewership of the color field tests was limited to RCA and CBS engineers and the invited press. The War Production Board halted the manufacture of television and radio equipment for civilian use from April 1, 1942 to October 1, 1945, limiting any opportunity to introduce color television to the general public. The post-war development of color television was dominated by three systems competing for approval by the FCC as the U.S. color broadcasting standard: CBS's field sequential system, which was incompatible with existing black and white sets without an adaptor; RCA's dot sequential system, which in 1949 became compatible with existing black and white sets; and CTI's system (also incompatible with existing black and white sets), which used three camera lenses, behind which were color filters that produced red, green, and blue images side by side on a single scanning tube, and a receiver set that used lenses in front of the picture tube (which had sectors treated with different phosphorescent compounds to glow in red, green, or blue) to project these three side by side images into one combined picture on the viewing screen. After a series of hearings beginning in September 1949, the FCC found the RCA and CTI systems fraught with technical problems, inaccurate color reproduction, and expensive equipment, and so formally approved the CBS system as the U.S. color broadcasting standard on October 11 1950. An unsuccessful lawsuit by RCA delayed the world's first network color broadcast until June 25 1951, when a musical variety special titled simply Premiere was shown over a network of five east coast CBS affiliates. Viewership was again extremely limited: the program could not be seen on black and white sets, and Variety estimated that only thirty prototype color receivers were available in the New York area. Regular color broadcasts began that same week with the daytime series The World Is Yours and Modern Homemakers. While the CBS color broadcasting schedule gradually expanded to twelve hours per week (but never into prime time), and the color network expanded to eleven affiliates as far west as Chicago, its commercial success was doomed by the lack of color receivers necessary to watch the programs, the refusal of television manufacturers to create adaptor mechanisms for their existing black and white sets, and the unwillingness of advertisers to sponsor broadcasts seen by almost no one. In desperation, CBS bought a television manufacturer, and on September 20, 1951, production began on the first and only CBS color television model. But it was too little, too late. Only 200 sets had been shipped, and only 100 sold, when CBS pulled the plug on its color television system on October 20, 1951, and bought back all the CBS color sets it could to prevent law suits by disappointed customers. Starting before CBS color even got on the air, the U.S. television industry, represented by the National Television System Committee, worked in 1950-1953 to develop a color system that was compatible with existing black and white sets and would pass FCC quality standards, with RCA developing the hardware elements. When CBS testified before Congress in March 1953 that it had no further plans for its own color system, the path was open for the NTSC to submit its petition for FCC approval in July 1953, which was granted in December. The first publicly announced experimental TV broadcast of a program using the NTSC-RCA "compatible color" system was an episode of NBC's Kukla, Fran and Ollie on August 30, 1953. NBC made the first coast-to-coast color broadcast when it covered the Tournament of Roses Parade on January 1 1954, with public demonstrations given across the United States on prototype color receivers. A few days later Admiral brought out the first commercially made color television set using the RCA standards, followed in March by RCA's own model. Television's first prime time network color series was The Marriage, a situation comedy broadcast live by NBC in the summer of 1954. NBC's anthology series Ford Theatre became the first color filmed series that October. NBC was naturally at the forefront of color programming because its parent company RCA manufactured the most successful line of color sets in the 1950s. CBS and ABC, which were not affiliated with set manufacturers, and were not eager to promote their competitor's product, dragged their feet into color, with ABC delaying its first color series (The Flintstones and The Jetsons) until 1962. The Du Mont network, although it did have a television-manufacturing parent company, was in financial decline by 1954 and was dissolved two years later. Thus the relatively small amount of network color programming, combined with the high cost of color television sets, meant that as late as 1964 only 3.1 percent of television households in the U.S. had a color set. NBC provided the catalyst for rapid color expansion by announcing that its prime time schedule for fall 1965 would be almost entirely in color (the exception being I Dream of Jeannie). All three broadcast networks were airing full color prime time schedules by the 1966–67 broadcast season. But the number of color television sets sold in the U.S. did not exceed black and white sales until 1972, which was also the first year that more than fifty percent of television households in the U.S. had a color set. In Mexico, Guillermo González Camarena (1917–1965), invented the early color television transmission system. He received patents for color television systems in 1940 (U.S. Patent 1942 (2296019), 1960 and 1962. The 1942 patent was for a mechanically scanned color filter adapter for an existing monochrome electronic transmission system. In August 31, 1946 he sent his first color transmission from his lab in the offices of The Mexican League of Radio Experiments in Lucerna St. #1, in Mexico City. The video signal was transmitted at a frequency of 115 MHz. and the audio in the 40 metre band. European color television was developed somewhat later and was hindered by a continuing division on technical standards. Having decided to adopt a higher-definition 625-line system for monochrome transmissions, with a lower frame rate but with a higher overall bandwidth, Europeans could not directly adopt the U.S. color standard, which was widely perceived as wanting anyway, because of its tint control problems. There was also less urgency, since there were fewer commercial motivations, European television broadcasters being predominantly state-owned at the time. As a consequence, although work on various color encoding systems started already in the 1950s, with the first SECAM patent being registered in 1956, many years had passed till the first broadcasts actually started in 1967. Unsatisfied with the performance of NTSC and of initial SECAM implementations, the Germans unveiled PAL (phase alternating line) in 1963, staying closer to NTSC but borrowing some ideas from SECAM. The French continued with SECAM, notably involving Russians in the development. The first regular colour broadcasts in Europe were by BBC2 beginning on July 1, 1967, using PAL. Germans did their first broadcast in September (PAL), while the French in October (SECAM). PAL was eventually adopted by West Germany, the UK, Australia, New Zealand, much of Africa, Asia and South America, and most Western European countries except France. In addition to France and Luxembourg, SECAM was adopted by Soviet Union, much of Eastern Europe, much of Africa and of the Middle East. Both systems broadcast on UHF frequencies, the VHF being used for legacy black and white, 405 lines in UK or 819 lines in France, till the beginning of the eighties. It should be noted that some British television programmes, particularly those made by or for ITC Entertainment, were made in colour before the introduction of colour television to the UK, for the purpose of sales to US networks. The first British show to be made in colour was the drama series The Adventures of Sir Lancelot (1956-57), which was initially made in black and white but later shot in colour for sale to the NBC network in the United States. In Japan, NHK introduced color television in the year 1960.

Broadcast television

NHK The first regularly scheduled television service in the United States began on July 2, 1928. The Federal Radio Commission authorized C.F. Jenkins to broadcast from experimental station W3XK in a suburb of Washington, D.C. But for at least the first eighteen months, only silhouette images from motion picture film were broadcast due to the narrow 10kHz bandwidth allotted by the FRC. General Electric's experimental station in Schenectady, New York, on the air sporadically since January 13, 1928, was able to broadcast reflected-light, 48-line images via shortwave as far as Los Angeles, and by September was making four television broadcasts weekly. CBS's New York City station W2XAB began broadcasting the first regular seven days a week television schedule in the United States on July 21, 1931, with a 60-line electromechanical system. The first broadcast included Mayor Jimmy Walker, the Boswell Sisters, Kate Smith, and George Gershwin. The service ended in February 1933. By 1935, electromechanical television broadcasting had ceased in the United States except for a handful of stations run by public universities that continued to 1939. The Federal Communications Commission saw television in the continual flux of development with no consistent technical standards, hence all such stations in the U.S. were granted only experimental and not commercial licenses, hampering television's economic development. Just as importantly, Philo Farnsworth's 1934 demonstration of an all-electronic system pointed the direction of television's future. On June 15, 1936, Don Lee Broadcasting began a month-long demonstration of all-electronic television in Los Angeles on W6XAO (later KTSL) with a 300-line image from motion picture film. RCA demonstrated in New York City a 343-line electronic television broadcast, with live and film segments, to its licensees on July 7, 1936, and made its first public demonstration to the press on November 6. By April 1939, regularly scheduled 441-line electronic television broadcasts were available in New York City and Los Angeles, and by November on General Electric's station in Schenectady. With the adoption of NTSC television engineering standards in 1941, the FCC saw television ready for commercial licensing, with the first such licenses issued to NBC and CBS owned stations in New York on July 1, 1941, followed by Philco's station in Philadelphia. Electromechanical broadcasts began in Germany in 1929, but were without sound until 1934. Network electronic service started on March 22, 1935, on 180 lines using only telecine transmission of film or an intermediate film system. Live transmissions began on January 15, 1936. The Berlin Summer Olympic Games were televised, using both direct television and intermediate film cameras, to 28 public television rooms in Berlin and Hamburg in August 1936. The Germans had a 441-line system on the air in February 1937, and during World War II brought it to France, where they broadcast off the Eiffel Tower. The first British television broadcast was made by Baird Television's electromechanical system over the BBC radio transmitter in September 1929. Baird provided a limited amount of programming five days a week by 1930. On August 22, 1932, BBC launched its own regular service using Baird's 30-line electromechanical system, continuing until September 11, 1935. On November 2, 1936 the BBC began broadcasting a dual-system service, alternating on a weekly basis between Marconi-EMI's 405-line standard and Baird's improved 240-line standard, from Alexandra Palace in London, making the BBC the world's first regular high-definition television service. The corporation decided that Marconi-EMI's electronic picture gave the superior picture, and the Baird system was dropped in February 1937. The outbreak of the Second World War caused the BBC service to be suspended on September 1, 1939, resuming from Alexandra Palace on June 7, 1946. The Soviet Union began offering 30-line electromechanical test broadcasts in Moscow on October 31, 1931, and a commercially manufactured television set in 1932. The first experimental transmissions of electronic television took place in Moscow on March 9, 1937, using equipment manufactured and installed by RCA. Regular broadcasting began on December 31, 1938. The first regular television transmissions in Canada began in 1952 when the CBC put two stations on the air, one in Montreal, Quebec on September 6, and another in Toronto, Ontario two days later. two days later The first live transcontinental television broadcast took place in San Francisco, California from the Japanese Peace Treaty Conference on September 4, 1951. In 1958, the CBC completed the longest television network in the world, from Sydney, Nova Scotia to Victoria, British Columbia. Reportedly, the first continuous live broadcast of a breaking news story in the world was conducted by the CBC during the Springhill Mining Disaster which began on October 23 of that year. Programming is broadcast on television stations (sometimes called channels). At first, terrestrial broadcasting was the only way television could be distributed. Because bandwidth was limited, government regulation was normal. In the U.S., the Federal Communications Commission allowed stations to broadcast advertisements, but insisted on public service programming commitments as a requirement for a license. By contrast, the United Kingdom chose a different route, imposing a television licence fee on owners of television reception equipment, to fund the BBC, which had public service as part of its Royal Charter. Development of cable and satellite means of distribution in the 1970s pushed businessmen to target channels towards a certain audience, and enabled the rise of subscription-based television channels, such as HBO and Sky. Practically every country in the world now has developed at least one television channel. Television has grown up all over the world, enabling every country to share aspects of their culture and society with others. By the late 1980s, 98% of all homes in the U.S. had at least one TV set. On average, Americans watch four hours of television per day. An estimated two-thirds of Americans got most of their news about the world from TV, and nearly half got all of their news from TV. These figures are now estimated to be significantly higher.

There are many means of distributing television broadcasts, including both analogue and digital versions of:
- Terrestrial television
- Stratovision (From aircraft flying in a loop)
- Satellite television
- Cable television
- MMDS (Wireless cable)

Receiving

Television sets

In television's electromechanical era, commercially made television sets were sold from 1928 to 1934 in the United Kingdom, United States, and Russia. The earliest commercially made sets sold by Baird in the U.K. and the U.S. in 1928 were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk (the Nipkow disk) with a spiral of apertures that produced a red postage-stamp size image, enlarged to twice that size by a magnifying glass. The "televisor" was also available without the radio. The Baird televisor sold in 1930-1933 is considered the first mass-produced set, selling about a thousand units. The first commercially made electronic television sets with cathode ray tubes were manufactured by Telefunken in Germany in 1934, followed by other makers in Britain (1936) and America (1938). The cheapest of the pre-War World II factory-made American sets, a 1938 image-only model with a 3-inch (8 cm) screen, cost US$125, the equivalent of US$1,732 in 2005. The cheapest model with a 12-inch (30 cm) screen was $445 ($6,256). An estimated 19,000 electronic television sets were manufactured in Britain, and about 1,600 in Germany, before World War II. About 7,000-8,000 electronic sets were made in the U.S. before the War Production Board halted manufacture in April 1942, which resumed in October 1945. Television usage in the United States skyrocketed after World War II with the lifting of the manufacturing freeze, war-related technological advances, the gradual expansion of the television networks westward, the drop in set prices caused by mass production, increased leisure time, and additional disposable income. While only 0.5% of U.S. households had a television set in 1946, 55.7% had one in 1954, and 90% by 1962. In Britain, there were 15,000 television households in 1947, 1.4 million in 1952, and 15.1 million by 1968. For many years different countries used different technical standards. France initially adopted the German 441-line standard but later upgraded to 819 lines, which gave the highest picture definition of any analogue TV system, approximately four times the resolution of the British 405-line system. Eventually the whole of Europe switched to the 625-line PAL standard, once more following Germany's example. Meanwhile in North America the original NTSC 525-line standard from 1941 was retained. NTSC Television in its original form involves sending images and sound over radio waves in the VHF and UHF bands, which are received by a television set. Over-the-air broadcast television requires an antenna (aerial). This can be an outdoor Yagi antenna. In strong signal areas the antenna can be indoors, attached to or near the receiver, such as an adjustable dipole antenna called "rabbit ears" for the VHF band and a small loop antenna for the UHF band.

Modern displays

Starting in the 1990s, modern television sets diverged into three different trends:
- standalone TV sets;
- integrated systems with DVD players and/or VHS VCR capabilities built into the TV set itself (mostly for small size TVs with up to 21" screen, the main idea is to have a complete portable system);
- component systems with separate big-screen video monitor, tuner, audio system which the owner connects the pieces together as a high-end home theater system. This approach appeals to videophiles who prefer components that can be upgraded separately. There are many kinds of video monitors used in modern TV sets. The most common are direct view CRTs for up to 40in (100cm) (in 4:3) and 46in (115cm) (in 16:9) diagonally; most big screen TVs (up to over 100 inch (254 cm)) use projection technology. Three types of projection systems are used in projection TVs: CRT-based, LCD-based, and DLP(reflective micromirror chip)-based. Modern advances have brought flat panels to TV that use active matrix LCD or plasma display technology. Flat panel LCDs and plasma displays are as little as 4in (10cm) thick and can be hung on a wall like a picture or put over a pedestal. They are multifunctional, because they are used like computer monitors too (VGA and DVI or HDMI connections). Some TVs integrate a pair of ports to connect computer cases and peripherals to it or to connect the set to an A/V home network (HAVI) (USB port for cord connection and BlueTooth/WiFi for wireless). Today, some LCD and Plasma sets have SD Card slots, so users can view pictures from a digital camera. On the new Panasonic LCDs and Plasmas (Viera), users have the capability to record onto SD card and then play it back on a hand-held PC or digital camera (anything that allows MPEG4). With SD cards now available with 1G of memory (soon 2GB, and Panasonic is also working on one that contains over 30GB of memory), a user can record over 1,000 minutes at low quality, and around 80 minutes on the highest quality. The playback of the recording is not brilliant, but these are the first generation. They will get better with time.

Signal connections

The number of ways to connect a video device to a television has increased over the years: WiFi
- HDMI - a compact 19 to 29 pin connector that carries digital video and digital audio signals. Essentially an enhanced version of DVI that includes digital audio. This is the most advanced form of connection currently available. DVI
- DVI - a 17 to 29 pin connector that carries digital video signals, designed to carry HDTV but also used in current DVD players and latest digital displays. Copy protection is available using HDCP. HDCP
- Component video - three separate RCA jacks (colored red, green and blue) carry three video signals, one brightness (luminance) and two colors (chromas), and is usually referred to as "Y, B-Y, R-Y", "Y Cr Cb" (interlaced) or "Y Pr Pb" (progressive), or YUV. Audio is not carried on this cable. This connection provides for picture quality superior to S-Video and is typically used in home theater for DVDs, satellite and analogue HDTV; less common in Europe but is starting to become more widely available. Europe
- SCART - a large 21 pin connector that may carry: one video signal composite video; or two video signals S-Video; or for picture quality similar to component video, three signals of separate red, green and blue or RGB; or for best picture quality, four video signals of separate red, green, blue and sync or RGBS; plus right and left line-level audio channels; along with a number of control signals including an aspect-ratio flag (e.g. widescreen). This system has been standard in Europe since mid-1980s for all consumer electronics, which meant that RGBS was available on even the earliest PAL DVD players and satellite receivers. Japan uses a 21 pin RGB connector which is visually similar to SCART but with different pin configurations. Japan
- S-Video - small round connector with two separate video signals, one carrying brightness (luminance), the other carrying color (chroma). Also referred to as Y/C video. Provides most of the benefit of component video, with slightly less color fidelity. Use started in the 1980s for S-VHS, Hi-8, and early NTSC DVD players to relay high quality video before component was available. Audio is not carried on this cable. Hi-8
- Composite video - The most common form of connecting external devices, putting all the video information into one signal. Most televisions provide this option with a yellow RCA jack. Audio is not carried on this cable, though two separate cables with similar red and white RCA jacks for right and left line-level audio are commonly bonded to composite video cables.
- Coaxial RF - All audio channels and picture components are transmitted through one coaxial cable and modulated on a radio frequency. Most TVs manufactured during the past 15–20 years accept coaxial connection, and the video is typically "tuned" on channel 3 or 4. This is the type of cable usually used for cable television. Most modern DVD players and other video devices no longer modulate RF output, so very old TV sets made before composite video jacks became commonplace will need a modulator.

Aspect ratios

Mechanically scanned television as first demonstrated by John Logie Baird in 1926 used a 7:3 vertical aspect ratio, oriented for the head and shoulders of a single person in close-up. Most of the early electronic TV systems from the mid-1930s onward shared the same aspect ratio of 4:3 which was chosen to match the Academy Ratio used in cinema films at the time. This ratio was also square enough to be conveniently viewed on round cathode-ray tubes (CRTs), which were all that could be produced given the manufacturing technology of the time. (Today's CRT technology allows the manufacture of much wider tubes, and the flat screen technologies which are becoming steadily more popular have no aspect ratio limitations at all.) The BBC's television service used a more squarish [http://tcc.members.beeb.net/tchistory.html 5:4] ratio from 1936 to circa 1949, when it too switched to a 4:3 ratio. In the 1950s, movie studios moved towards widescreen aspect ratios such as Cinerama in an effort to distance their product from television. Although this was initially just a gimmick widescreen is still the format of choice today and square aspect ratio movies are rare. Some people argued that widescreen is actually a disadvantage when showing objects that are tall instead of panoramic, others would say that natural vision is more panoramic than tall, and therefore widescreen is easier on the eye. The switch to digital television systems has been used as an opportunity to change the standard television picture format from the old ratio of 4:3 (approximately 1.33:1) to an aspect ratio of 16:9 (approximately 1.78:1). This enables TV to get closer to the aspect ratio of modern widescreen movies, which range from 1.78:1 through 1.85:1 to 2.35:1. There are two methods for transporting widescreen content, the better of which uses what is called anamorphic widescreen format. This format is very similar to the technique used to fit a widescreen movie frame inside a 1.33:1 35mm film frame. The image is squashed horizontally when recorded, then expanded again when played back. The anamorphic widescreen 16:9 format was first introduced via European PAL-Plus television broadcasts and then later on "widescreen" DVDs; the ATSC HDTV system uses straight widescreen format, no image squashing or expanding is used. Recently "widescreen" has spread from television to computing where both desktop and laptop computers are commonly equipped with widescreen displays, and it remains to be seen whether Work or movie enjoyment will take over. There are some complaints about distortions of movie picture ratio due to some DVD playback software not taking account of aspect ratios; but this will subside as the DVD playback software matures. Furthermore, computer and laptop widescreen displays are in the 16:10 aspect ratio both physically in size and in pixel counts, and not in 16:9 of consumer televisions, leading to further complexity. This was a result of widescreen computer display engineers' uninformed assumption that people viewing 16:9 content on their computer would prefer that an area of the screen be reserved for playback controls or subtitles, as opposed to viewing content full-screen.

Aspect ratio incompatibility

The television industry changing aspect ratios is not without teething difficulties, and can present a considerable problem. Displaying a widescreen aspect (rectangular) image on a conventional aspect (square) display can be shown:
- in "letterbox" format, with black horizontal bars at the top and bottom
- with part of the image being cropped, usually the extreme left and right of the image being cut off (or in "pan and scan", parts selected by an operator)
- with the image horizontally compressed A conventional aspect (square) image on a widescreen aspect (rectangular) display can be shown:
- in "pillarbox" format, with black vertical bars to the left and right
- with upper and lower portions of the image cut off
- with the image horizontally distorted A common compromise is to shoot or create material at an aspect ratio of 14:9, and to lose some image at each side for 4:3 presentation, and some image at top and bottom for 16:9 presentation. Horizontal expansion has advantages in situations in which several people are watching the same set, as it compensates for watching at an oblique angle.

Advertising

Since their inception in the USA in 1941, TV commercials have become one of the most effective, most pervasive, and most popular methods of selling products of many sorts, especially consumer goods. U.S. advertising rates are determined primarily by Nielsen ratings. The exception to this is the publicly-funded British Broadcasting Corporation.

Programming

Getting TV programming shown to the public can happen in many different ways. After production the next step is to market and deliver the product to whatever markets are open to using it. This typically happens on two levels: #Original Run or First Run - a producer creates a program of one or multiple episodes and shows it on a station or network which has either paid for the production itself or to which a license has been granted by the producers to do the same. #Syndication - this is the terminology rather broadly used to describe secondary programming usages (beyond original run). It includes secondary runs in the country of first issue, but also international usage which may or may not be managed by the originating producer. In many cases other companies, TV stations or individuals are engaged to do the syndication work, in other words to sell the product into the markets they are allowed to sell into by contract from the copyright holders, in most cases the producers. In most countries, the first wave occurs primarily on FTA television, while the second wave happens on subscription TV and in other countries. In the U.S. however, the first wave occurs on the FTA networks and subscription services, and the second wave travels via all means of distribution. First run programming is increasing on subscription services outside the U.S., but few domestically produced programs are syndicated on domestic FTA elsewhere. This practice is increasing however, generally on digital only FTA channels, or with subscriber-only first run material appearing on FTA. Unlike the U.S., repeat FTA screenings of a FTA network program almost only occur only on that network. Also, affiliates rarely buy or produce non-network programming that isn't intensely local.

Social aspects

Alleged dangers

Paralleling television's growing primacy in family life and society, an increasingly vocal chorus of legislators, scientists and parents are raising objections to the uncritical acceptance of the medium. For example, the Swedish government imposed a total ban on advertising to children under twelve in 1991 (see advertising). In the U.S., the [http://www.mediafamily.org/facts/facts_tveffect.shtml National Institute on Media and the Family] (not a government agency) points out that U.S. children watch an average of 25 hours of television per week and features studies showing it interferes with the educational and maturational process. A February 23 2002 article in [http://www.sciam.com/print_version.cfm?articleID=0005339B-A694-1CC5-B4A8809EC588EEDF Scientific American] suggested that compulsive television watching was no different from any other addiction, a finding backed up by reports of withdrawal symptoms among families forced by

:This article is about computer and video games. For the magazine see Computer and Video Games (magazine). Technically, a computer game is a game composed of a computer-controlled virtual universe that players may interact with in order to achieve a goal (or set of goals). A video game is a computer game where a video display is the primary feedback device. Since nearly all computer games use some sort of visual display, these terms are usually considered interchangeable, and are frequently used as umbrella terms for interactive game software. The phrase interactive entertainment is the formal reference to computer and video games. To avoid ambiguity, this game software is referred to as "computer and video games" throughout this article. However, in common usage, "computer game" refers more specifically to games played on a personal computer, while "video game" (or "videogame") actually refers to both, and "[console name] game" refers specifically to games played on a particular console.

History

The first primitive computer and video games were developed in the 1950s and 1960s and ran on platforms such as oscilloscopes, university mainframes and EDSAC computers. Arcade games were developed in the 1970s and led to the so-called "Golden Age of Arcade Games". One of the most well-known of these games is Pong. The 1970s also saw the release of the first home video game consoles. The late 1970s to early 1980s brought about the improvement of home consoles and the release of the Atari 2600, Intellivision and Colecovision. The video game crash of 1983, however, produced a dark age in the market that was not filled until the Nintendo Entertainment System (NES) reached North America in 1985. The last two decades of game history have been marked by separate markets for games on video game consoles, home computers and handhelds. See the article on Console wars for additional information on that facet of game history.

The future of console gaming

The end of 2005 and first and second quarters of 2006 will see the next generation of console gaming in the form of continuing advances in processor technology, graphics technology, design innovation, and even platform specific gaming community infrastructure. Sony, Nintendo, and Microsoft are all participating in this coming year's "technology race". The second generation Microsoft offering, the Xbox 360, will be powered by a multi-core CPU, the PlayStation 3 will be powered by Cell processor technology, and the Nintendo Revolution will allow the gamer to interact with the game via a wireless motion sensing controller, although full technical specifications are yet to be revealed.

Gameplay

Main article: Gameplay In computer and video gaming, gameplay (sometimes called "Game mechanics") is a general term that describes player interaction with a game. It includes direct interaction, such as controls and interface, but also design aspects of the game, such as levels. Although the use of this term is often disputed, as it is considered too vague for the range of concepts it describes, it is currently the most commonly used and accepted term for this purpose when describing video games.

Genres

Main article: Computer and video game genres Games, like most other forms of media, may be categorized into genres based on gameplay, atmosphere, and various other factors. Any individual gamer is likely to favor some types of gameplay over others, these are refered to as video game genres. The most common genres in use today include platformers, adventure, role-playing games (RPGs), first person shooters (FPS), third person shooter (sometimes called shoot 'em ups), sports, racing, fighting (sometimes called beat 'em ups), action (although this term is abused), puzzle, simulation, and real time strategy (RTS), to name a few. It is rare that a game will fall purely into one genre, most games are a combination of two or more genres (e.g action/RPG). Although most genres have 2D counterparts, they are for the most part considered entirely different genres because of the differences in the way 2D and 3D games are played (e.g. Super Mario Bros. and Super Mario 64). The increase in the popularity of online gaming has also resulted in new sub-genres being formed, such as the massively multiplayer online role-playing game.

Gaming platforms

massively multiplayer online role-playing game Today there are many different devices that games may be played on. Personal computers, consoles, handheld systems, and arcade machines are all common. There is an extremely thin line between games played on the computer and those on the console, which is a standardized computer with little or no setup. Many games intended for computer are now just as prevalent on consoles, both of which have many of the same titles. This is due to the fact that video game consoles have drastically increased in computing power and capabilities over the last few years to the point that they can handle games that were formerly only playable with comparatively higher-end computers. During the last generation of gaming, most major computer game releases have coincided with the release of console versions, and titles initially developed for a single platform are often ported to others if they prove to be successful.

Personal Computer

Main article: Personal Computer Games Personal computer games are commonly referred to as "computer games" or "PC games". They are played on the personal computer with standard computer interface devices such as the keyboard and mouse, or additional peripherals, such as joysticks. Video feedback is received by the user through the computer screen, sound through speakers or headphones. Computer games are often more powerful than console games because of early market releases of their external architecture and graphics cards. The most popular genres of Computer games are First-Person Shooters, Real-Time Strategy, Simulations, and MMOGs, given the long-standing nature of Internet access and online play. First Person Shooters benefit highly from using the keyboard and mouse to give very fine control over player movement that is still not matched on the consoles. Today, most PC games require the Windows operating system to be installed on the computer. There is, however, a continuing movement to get the most popular games to run under the Mac and Linux operating systems. According to the Entertainment Software Association, console games have outsold computer games roughly four units to one in 2003 and 2004 [http://theesa.com/facts/sales_genre_data.php]. For more information, see sales. One possible explanation for the declining sales of personal computer games in relation to that of consoles can be found within the PC itself: a computer must meet certain minimum requirements (listed on retail box of the title) such as CPU speed, memory, video card memory, hard drive space, operating system, Internet connection speed (for online games) and other criteria. Without the proper hardware, the game may perform poorly or not run at all.

Internet

Main article: Internet gaming Online Games are those which either require or benefit from a connection to the Internet to play. Online gaming began with PC games, but has over time expanded to include most moder consoles. It is now a key feature of modern games, with the inclusion of Internet connectivity in consoles such as the PlayStation 2 and Xbox, and in mobile/cellular phones. Online games need to allow several people to play at the same time, so not all genres are suitable; the most popular genres include MMORPG's, FPS's, racing/driving games, strategy games, and sports titles. The Internet is also host to thousands of small Flash and Java games, named after the programming language in which they are written. These games generally do not share the same magnitude of development costs, depth, or seriousness of PC and console games, and are generally quick to complete by comparison. Some of these games, such as Runescape, however, have expanded far beyond this, and can often be considered on the same level as "mainstream" PC games.

Console

Main article: Console games Console games are played video game console, a specialized computer specifically designed to play games of a certain format. The player usually interacts with the game through a controller, and video and sound are typically delivered to the player via a television, although most modern consoles support additional outputs, such as surround sound setups. Consoles themselves branched off from personal computers around two decades ago, a fact which is still evident not only in the name, but also in many of the peripherals available for many consoles, like the keyboard and mouse peripherals released for the Sony PlayStation 2 and the Sega Dreamcast.

Handheld

Main article: Handheld video games Handheld games are played on handheld game consoles, such as the Nintendo Gameboy, Nintendo DS, and Sony PSP. Handheld consoles act as their own controllers, which the player uses to interact with the game, as well as having in-built display and audio output devices. Because they are designed to be played on the go, they are usually small enough to fit into an average pocket (the virtual boy is an exception to this), but due to their small size, haldheld consoles have reduced processing power compared to larger consoles, meaning that games are shorter, and until the release of the DS, were limited to 2D.

Mobile Phone

Main article: Mobile/Cellular Phone Games Most mobile phones now have games built into them, and others are available for download, or can be bought for a small amount of money. These games are more restricted than traditional handheld games, and usually play more like arcade games.

Arcade

Main article: Arcade Games Arcade games, traditionally, are "coin-operated games", played on a standalone device originally leased to commercial entertainment venues. These are programmed, equipped, and decorated for a specific game, consisting of a video display, a set of controls, and the coin slot. Controls are similar to those available for many consoles (albeit usually as peripherals) and range from the classic joystick and buttons, to light guns, to pads on the ground that sense pressure. Arcade games that are no longer profitable to lease can be purchased by private individuals, many of whom then explore the game dynamics by altering the programs. This term has now expanded to include any game that has more direct action, with fewer long term objectives and, for the most part, shorter in-game levels.

Popularity

:What rock and roll was to the youth of the Sixties, gaming is to the youth of today. — Killol Bhuta, brand manager, Ford Motor Company [http://www.edmunds.com/insideline/do/Features/articleId=107487] The popularity of computer and video games, as a whole, has been increasing steadily ever since the 1984-1987 dropoff caused by the video game crash of 1983, and the popularity appears to be continuing to increase. The average age of the video game player is now 29 [http://biz.gamedaily.com/features.asp?article_id=8540&filter=myturn], belying the myth that video games are largely a diversion for teenagers.

Sales

teenager) with a large selection of games for several major consoles]] The four largest markets for computer and video games are the United States, Japan, Canada and the United Kingdom. Other significant markets include Spain, Germany, South Korea, France, and Italy. China is not considered a significant market, most likely because an estimated 95% of video games sold in the country are pirated. [http://slate.msn.com/id/2116629/] Sales of different types of games vary widely between these markets due to local preferences. Japanese consumers avoid computer games and instead buy video games, with a strong preference for games created in Japan, that run on Japanese consoles. In South Korea, computer games are preferred, especially MMORPG games and real-time strategy games; there are over 20,000 PC bang Internet cafes where computer games can be played for an hourly charge. The NPD Group tracks computer and video game sales in the United States. It reported that as of 2004:
- Console and portable software sales: $6.2 billion, up 8% from 2003 [http://gameinfowire.com/news.asp?nid=5650]
- Console and portable hardware and accessory sales: $3.7 billion, down 35% from 2003 [http://gameinfowire.com/news.asp?nid=5650]
- PC game sales: $1.1 billion, down 2% from 2003 [http://www.gamespot.com/news/2005/01/28/news_6117438.html] These figures are sales in dollars, not units; unit shipments for each category were higher than the dollar sales numbers indicate, as more software and hardware was sold at reduced prices compared to 2003. Retail PC game sales have been declining slightly each year since about 1998, but this fact should be taken with a grain of salt: the retail sales numbers from NPD do not include sales from online downloads, nor subscription revenue for games like MMORPGs. There is a commonly repeated, mistaken belief that video game sales now exceed the revenues of the movie industry. This is untrue; in the United States, video game sales have exceeded the movies' total box office revenue each year since about 1996, but the movie studios trounce the video game publishers when the movies' "ancillary revenue" is counted, meaning sales of DVDs, sales to foreign distributors, and sales to cable TV, satellite TV, and broadcast television networks. The game and film industries are also becoming increasingly intertwined, with companies like Sony having significant stakes in both. A large number of summer blockbuster films spawn a companion game, often launching at the same time in order to share the marketing costs.

Computer and video games in the broader culture

Computer games are huge business worldwide. Take for example South Korea. Developers there boast MMORPGs such as Lineage and Ragnarok Online with millions of subscribers and a third of the world's MMOG revenue. StarCraft gosu (expert players) are celebrities in a game that some have called the country's national sport. The success of computer and online gaming there is usually credited to South Korea's push for broadband Internet connections in the home and earlier bans on Japanese products (these restrictions were removed by the late 1990s). Numerous websites and publications devoted solely to games have been created, including Official Xbox Magazine, Nintendo Power, Official Playstation Magazine, GamePro, GameSpot, GameSpy, IGN and GameFAQs. Video gaming now ingrained in popular culture in the United States. Many T-shirts are available that directly reference video games, such as one with a picture of an NES controller with the text 'Know Your Roots.' Also, video games have also become a major part in cross marketing platforms, such as in Pokémon or Yu-Gi-Oh, where a child can watch the television show, buy the trading cards, and play the various video games available. Video game properties have had mixed success when migrating to the movies. One of the first films based on a video game property was The Wizard, which some criticized as a 90-minute ad for Super Mario Brothers 3. In the mid-90s, films for Super Mario Brothers, Street Fighter, Wing Commander and Mortal Kombat were released. Reviews have generally been poor. Despite the ultimately poor performance of these movies, many studios still want to turn big games into movies, hoping that the popularity of the game will help the movie. However, after the initial bunch, many projects materialized that were never finished, but the success of films like Lara Croft: Tomb Raider has led to more films materializing. Doom, a game which film makers were trying to cross over since the mid '90s, finally hit theatres 12 years after its initial release. John Woo is also producing a movie on the popular Nintendo game Metroid. There is still debate in the movie industry on whether video games can consistently be turned into good, profitable movies. Films like Final Fantasy: The Spirits Within, which has received mixed responses from audiences, with some saying it is a great movie, and others saying it is a very bad movie with excellent computer-generated imagery, but ultimately flopped in the box office, and Uwe Boll's House of the Dead and Alone in the Dark, which both ended up being horrible flops both in fan reactions and box office success and both ending up on the IMDB's bottom 100 movies, do not, in turn, give much confidence in whether these movies will be handled seriously. The recently released Final Fantasy VII: Advent Children may change some people's minds though, even though it's a straight to DVD affair. On the other hand, video games get much more success when adapted into cartoons/animes. Some notables examples of major success includes the various Mario Bros. cartoons, Sonic SatAM, Captain N: The Game Master and Earthworm Jim while Sonic Underground, the American Mega Man cartoon and 4Kids' dubs (although this isn't limited to their video game-based dubs) are cited as being poor. Sometime, they even "help" more obscure/Japan-only games pick up popularity in America although rarely; To Heart would be the best example of such thing. Movies have had far more success moving the other direction, onto video games. Most summer blockbuster films now have a simultaneous video game release; some of the most lucrative video games of recent times are based on movies, such as Electronic Arts' and Stormfront Studios' The Lord of the Rings: The Two Towers and the series of EA LotR games that followed it, and Activision's two Spider-Man movie games. Even though movies have had more success in game conversion, not all movie games are popular amongst the gaming community. Some publishers believe that the success of the movie will help the game sell, and so may not have as lengthy a development schedule as needed to make a compelling game. Some examples of this are the Catwoman and King Arthur movie games. Also, video games have found themselves on MTV2, in a popular show called Video Mod, where characters from popular video games perform songs from hit artists, such as characters from The Sims 2 performing the song "Stacy's Mom" by Fountains Of Wayne. On the Internet, gaming has also become a popular subject of many webcomics. Currently there are two varieties. The first one is the sprite comic, such as 8 Bit Theatre, in which the artist uses sprites from the earlier Final Fantasy games to tell stories. Sometimes these are original stories, but are often parodies of the game in which the sprite came from. The other is a more traditional comic strip, containing original art, like Penny Arcade. Here, the storylines or jokes revolve around current events in video gaming. The success of Penny Arcade has attracted many people in the industry, including Ubisoft. Other parodies have come in the form of amateur videos, such as those of Mega 64. In Germany, the TV channel NBC Europe broadcasts a show called GIGA, which turned more and more into a video and computer game show. In the show, new games are presented and reviewed. Lately, the show featured the esports scene a lot, by introducing professional players to the audience and broadcasting live competition matches. Online shows are fast becoming the place to view live action gaming broadcasts such as gamespot's 'On the Spot'

Development

Main article: Game development Video games are made by developers, who used to do this as individuals in the 80's (Bedroom Coders) , but now are almost always a large team consisting of designers, graphic designers and other artists, programmers, sound designers, musicians, and other technicians. Video games are developing fast in all areas, but the problem is of price and how developers intend to keep the price where it is while incorporating better technology, that inevitably costs more. Most video game console development teams number anywhere from 20 to 50 people, with some teams exceeding 100. The average team size as well as the average development time of a game have grown along with the size of the industry and the technology involved in creating games. This has led to regular occurrences of missed deadlines and unfinished products; Duke Nukem Forever is the quintessential example of these problems. See also: video game industry practices.

Game modifications

Main article: Mod (computer gaming) Games running on a PC are often designed with end-user modifications in mind, and this consequently allows modern computer games to be modified by gamers without much difficulty. These mods can add an extra dimension of replayability and interest. The Internet provides an inexpensive medium to promote and distribute mods, and they have become an increasingly important factor in the commercial success of some games. Developers such as id, Valve, and Epic provide extensive tools and documentation to assist mod makers, allowing for the kind of success seen by popular mods such as Counter-Strike. Popular mods are sometimes bought by the developers of the game. This is the case of Valve's Half-life. They bought a number of popular mods including Counter-strike and Day of defeat. After the release of Half-life 2 Valve developed these mods for the sequel and sold them through their digital distribution software Steam through the internet. Recently, computer games have also been used as a digital art medium. See artistic computer game modification.

Naming

Gamers use several umbrella terms for console, PC, arcade, handheld, and similar games since they do not agree on the best name. For many, either "computer game" or "video game" describes these games as a whole. Other commonly used terms include, "entertainment software," "interactive entertainment media," "electronic interactive entertainment," "electronic game," "software game," and "videogame" (as one word). Computer and video games may be considered a subset of interactive media, which includes virtual reality, flight and engineering simulation, multimedia and the World Wide Web.

The Internet

:For the more general networking concept, see internetworking. The Internet, or simply the Net, is the worldwide system of interconnected computer networks which makes information stored on it accessible. This information is transmitted by packet switching using a standardized Internet Protocol (IP) and many other protocols. It is made up of thousands of smaller commercial, academic, domestic and government networks. It carries various information and services, such as electronic mail, online chat, and the interlinked web pages and other documents of the World Wide Web.

Creation of the Internet

During the 1950s, several communications researchers realized that there was a need to allow general communication between users of various computers and communications networks. This led to research into decentralized networks, queuing theory, and packet switching. The subsequent creation of ARPANET in the United States in turn catalyzed a wave of technical developments that made it the basis for the development of the Internet. Contrary to popular myth, the DoD did not create the ARPANET so that they could communicate to the US Government after a nuclear war. The first TCP/IP wide area network was operational in 1984 when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. It was then followed by the opening of the network to commercial interests in 1995. Important separate networks that offered gateways into, then later merged into the Internet include Usenet, Bitnet and the various commercial and educational X.25 networks such as Compuserve and JANET. The ability of TCP/IP to work over these pre-existing communication networks allowed for a great ease of growth. Use of Internet as a phrase to describe a single global TCP/IP network originated around this time. The collective network gained a public face in the 1990s. In August 1991 CERN in Switzerland publicized the new World Wide Web project, two years after Tim Berners-Lee had begun creating HTML, HTTP and the first few web pages at CERN in Switzerland. In 1993 the Mosaic web browser version 1.0 was released, and by late 1994 there was growing public interest in the previously academic/technical Internet. By 1996 the word "Internet" was common public currency, but it referred almost entirely to the World Wide Web. Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network.

Today's Internet

FidoNets, FTP client, and Telnet client]] Apart from the complex physical connections that make up its infrastructure, the Internet is held together by bi- or multi-lateral commercial contracts (for example peering agreements) and by technical specifications or protocols that describe how to exchange data over the network. Indeed, the Internet is essentially defined by its interconnections and routing policies. In an often-cited, if perhaps gratuitously mathematical definition, Seth Breidbart once described the Internet as "the largest equivalence class in the reflexive, transitive, symmetric closure of the relationship 'can be reached by an IP packet from'". Unlike older communications systems, the Internet protocol suite was deliberately designed to be independent of the underlying physical medium. Any communications network, wired or wireless, that can carry two-way digital data can carry Internet traffic. Thus, Internet packets flow through wired networks like copper wire, coaxial cable, and fiber optic; and through wireless networks like Wi-Fi. Together, all these networks, sharing the same high-level protocols, form the Internet. The Internet protocols originate from discussions within the Internet Engineering Task Force (IETF) and its working groups, which are open to public participation and review. These committees produce documents that are known as Request for Comments documents (RFCs). Some RFCs are raised to the status of Internet Standard by the Internet Architecture Board (IAB). Some of the most used protocols in the Internet protocol suite are IP, TCP, UDP, DNS, PPP, SLIP, ICMP, POP3, IMAP, SMTP, HTTP, HTTPS, SSH, Telnet, FTP, LDAP, SSL, and TLS. Some of the popular
