- Pong (Wikipedia)
Pong is a table tennis–themed twitch arcade sports video game, featuring simple two-dimensional graphics, manufactured by Atari and originally released on 29 November 1972. It is one of the earliest arcade video games; it was created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell, but Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn’s work and decided to manufacture the game. Bushnell based the game’s concept on an electronic ping-pong game included in the Magnavox Odyssey, the first home video game console. In response, Magnavox later sued Atari for patent infringement.
