Despite the fact that computers were not invented for playing games, the idea that they could be used for games did not take long to emerge. Alan Turing proposed a famous game called “Imitation Game” in 1950. In 1952, Rand Air Defense Lab in Santa Monica created the first military simulation games. In 1953, Arthur Samuel (1901–1990) created a checkers program on the new IBM 701. From these beginnings computer games have today become a multi-billion-dollar industry.
