The name ping-pong was in wide use before English manufacturer J. Jaques & Son Ltd trademarked it in 1901. The name Ping-Pong then came to be used for the game played by the rather expensive Jaques equipment, with other manufacturers calling theirs table tennis.
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 game was originally manufactured by Atari, which released it in 1972. Allan Alcorn created Pong as a training exercise assigned to him by Atari co-founder Nolan Bushnell. Bushnell based the idea on an electronic ping-pong game included in the Magnavox Odyssey, which later resulted in a lawsuit against Atari.
