Early history of video games
The history of video games spans a period of time between the invention of the first electronic games and today, covering a long period of invention and changes. Video gaming reached mainstream popularity in the 1970s and 1980s, when arcade video games, gaming consoles and home computer games were introduced to the general public. Since then, video gaming has become a popular form of entertainment and a part of modern culture in most parts of the world. The early history of video games, therefore, covers the period of time between the first interactive electronic game with an electronic display in 1947, the first true video games in the early 1950s, and the rise of early arcade video games in the 1970s ("Pong" and the beginning of the first generation of video game consoles with the Magnavox Odyssey, both in 1972). During this time there were a wide range of devices and inventions corresponding with large advances in computing technology, and the actual first video game is dependent on the definition of "video game" used.
Magnavox Odyssey
In May 1972, Nutting Associates chief engineer Nolan Bushnell, designer of the first commercial arcade video game, "Computer Space", saw a demonstration of the Odyssey at a dealership. Inspired, when he quit Nutting to start his own company, Atari, he assigned Allan Alcorn to create a cheap ping pong arcade game as a training exercise, though he did not tell Alcorn that it was for training nor that the idea was based on the Odyssey "Table Tennis" game. Alcorn soon developed "Pong", which Bushnell recognized as a potential hit, and it became the company's first game. "Pong" was very successful, and in turn helped drive sales of the Odyssey; Baer once noted that customers bought the console because of "Table Tennis", in turn because of "Pong", and joked that they may as well have stopped designing games after that game card. In 1974, however, Magnavox sued Atari along with several competitors including Nutting, Allied Leisure, Bally Midway, and Williams Electronics for infringing on Baer's patents for video games played on a television screen. Baer has stated that the lawsuits were not filed right away because Magnavox and Sanders needed to wait until they could expect to be awarded more money than it would cost to pursue the suits. The root of the conflict was a pair of patents by Baer—one which described how the Odyssey showed player-controlled objects, or dots, on a video monitor and described a number of games that could be played with the system, and an earlier one that went into detail about how the Odyssey used that system to have two dots collide with each other and have one bounce off, specifically using a game of ping pong as an example.
