"Spacewar!" inspired the first two arcade video games; "Galaxy Game", a demonstration coin-operated unit run at Stanford University in November 1971, "Computer Space", the first commercial arcade game created by Nolan Bushnell and Ted Dabney in the same month. Bushnell and Dabney followed their success of "Computer space" with the help of Allan Alcorn to create a table tennis game "Pong", released in 1972. "Pong" was a commercial success, leading to numerous other coin-op manufacturers to enter the market and create the arcade game industry.
