magnavox 1 00magnavox 1 01The Magnavox Odyssey is the first commercial home video game console. The hardware was designed by a small team led by Ralph H. Baer at Sanders Associates, while Magnavox completed development and released it in the United States in September 1972 and overseas the following year. The Odyssey consists of a white, black, and brown box that connects to a television set, and two rectangular controllers attached by wires. It is capable of displaying three square dots and one line of varying height on the screen in monochrome black and white, with differing behavior for the dots depending on the game played. Players place plastic overlays on the screen to display additional visual elements for each game, and the one or two players for each game control their dots with the knobs and buttons on the controller in accordance with the rules given for the game. The console cannot generate audio or track scores. magnavox 1 02The Odyssey console came packaged with dice, paper money, and other board game paraphernalia to accompany the games, while a peripheral controller—the first video game light gun—was sold separately.

The idea for a video game console was conceived by Baer in August 1966. Over the next three years he, along with Bill Harrison and Bill Rusch, created seven successive prototype consoles. The seventh, known as the Brown Box, was shown to several manufacturers before Magnavox agreed to produce it in January 1971. After releasing the console through their dealerships, Magnavox sold 69,000 units in its first calendar year and 350,000 by the time the console was discontinued in 1975. magnavox 1 03The console spawned the Odyssey series of dedicated consoles as well as the 1978 Magnavox Odyssey 2. One of the 28 games made for the system, a ping pong game, was an inspiration for Atari's successful 1972 Pong arcade game, in turn driving sales of the Odyssey. Patents by Baer and the other developers for the system and the games, including what was termed by a judge as "the pioneering patent of the video game art", formed the basis of a series of lawsuits spanning 20 years, earning Sanders and Magnavox over US$100 million. The release of the Odyssey marked the beginning of the first generation of video game consoles and was an early part of the rise of the commercial video game industry.

  In 1975, Atari and Magnavox started selling improved systems using integrated circuits. Magnavox used      several Texas Instruments (TI) chips, which replicated the design of the first Odyssey, itself based on 1967 transistor circuits. Atari, however, had the smart idea of designing the first "PONG in a chip" device, but these Atari chips were not available to other manufacturers, thus limitating the market considerably. Most Atari systems used a different chip because of the different games and features. Of course, a few discrete components interfaced the chip to the other parts of the system: the video modulator, the player controls, etc. These chips replaced most of the numerous components used in the early analog and digital systems. Although Atari chips were a smart design, the idea of integrating complex circuits into a single chip was a common idea at that time, and other video game manufacturers soon released their own video game chips.
 

Texas Instruments (TI) had an important role in 1975 since Magnavox asked the manufacturer to design a special chip set for the Odyssey 100 and later models. Each chip had a special function: paddle generator, collision detection, on-screen scoring, etc. They are detailed in the table at the end of this page. These chips were the SN764xx. It was possible to combine these chips to design a customised Ball & Paddle games, and even a Spacewar game.

Later, TI copied the Executive Games Television Tennis circuits and integrated them into a new chip: the SN76410N. This chip was very unsuccessfull and very few systems used it: Tele-Match 3300R, Ricochet Super Pro (model MT-4A), and Venture Electronics Video Sports VS-5. David Winter asked Glen Dash (who designed the Television Tennis) how this came to his attention. His reply was crystal clear: "The Tennis game was absolutely same, so much that it had the same bugs as my original design".

Because all these chips were unsuccessfull, TI decided to release another type of chip in 1977: the TMS-1955 and TMS-1965, both pin compatible with the GI AY-3-8500, hence a better success.
