Video games have been around since the early 1970’s. The first commercial arcade video game, Computer Space by Nutting Associates, was introduced in 1971. In 1972, Atari introduced Pong to the arcades. An interesting item to note is that Atari was formed by Nolan Bushnell, the man who developed Computer Space. He left Nutting Associates to found Atari, which then produced Pong, the first truly successful commercial arcade video game.
