In 1971 students at Stanford University set up the "Galaxy Game", a coin-operated version of the Spacewar video game. This ranks as the earliest known instance of a coin-operated video game. Later in the same year, Nolan Bushnell created the first mass-manufactured game, "Computer Space", for Nutting Associates. In 1972, Atari was formed by Nolan Bushnell and Ted Dabney. 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

They jointly developed the concept of using a standalone computer system with a monitor and attaching a coin slot to it to play games on. Bushnell and Dabney worked with Nutting Associates to manufacture their product. Dabney developed a method of using video circuitry components to mimic functions of a computer for a much cheaper cost and a smaller space. Bushnell and Dabney used this to develop a variation
