Pong is a table tennis sports game featuring simple two-dimensional graphics, manufactured by Atari and originally released in 1972. It was one of the earliest arcade video games and created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell. 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. Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn's work and decided to manufacture the game.
