As part of the project, Douglas created the first graphical computer game: a version of Tic-Tac-Toe. The game was programmed on an EDSAC vacuum-tube computer, which had a cathode ray tube display. In 1958, William Higinbotham created the first video game ever. His game, titled Tennis for Two, was created and played on a Brookhaven National Laboratory oscilloscope. In 1962, Steve Russell invented SpaceWar!, which was the first game intended for computer use. Russell used an MIT PDP-1 mainframe computer to design his game. In 1967, Ralph Baer wrote the first video game played on a television set, a game called Chase. Baer, who was then part of Sanders Associates, a military electronics firm, first conceived of his idea in 1951 while working for Loral, a television company.
