Atari essentially created the coin-operated video game industry with the game "Pong", the first successful electronic ping pong video game. "Pong" proved to be popular, but imitators
Computer Space Ted Dabney "Spacewar" at the Stanford laboratory, and the two agreed to work together to try and design a prototype of the game; Bushnell was more experienced with computers and digital engineering, while Dabney was more experienced with analog and hardware engineering, as he had been working on designing video processing and control circuits and power supplies. After agreeing on an initial idea, Bushnell and Dabney began trying to design a prototype based on a Data General Nova. Initially they were joined by Larry Bryan, a computer programmer who also worked at Ampex. Bushnell and Dabney put US$100 each into
