Pong (marketed as PONG) is one of the earliest arcade video games, and is a tennis sports game featuring simple two-dimensional graphics. While other arcade video games such as Computer Space came before it, Pong was one of the first video games to reach mainstream popularity. The aim is to defeat your opponent in a simulated table tennis game by earning a higher score. The game was originally manufactured by Atari Incorporated (Atari), who released it in 1972. Pong was created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell.
