Early history of video games
Throughout the rest of the 1960s, digital computer games were created by increasingly numerous programmers and sometimes sold commercially in catalogs. As the audience for video games expanded to more than a few dozen research institutions with the falling cost of computers, and programming languages that would run on multiple types of computers were created, a wider variety of games began to be developed. Video games transitioned into a new era in the early 1970s with the launch of the commercial video game industry in 1971 with the display of the coin-operated arcade game "Galaxy Game" and the release of the first arcade video game "Computer Space", and then in 1972 with the release of the immensely successful arcade game "Pong" and the first home video game console, the Magnavox Odyssey, which launched the first generation of video game consoles.
History of video games
The earliest known electronic computer games actually implemented were two custom built machines called "Bertie the Brain" and Nimrod, which played tic-tac-toe and the game of Nim, respectively. "Bertie the Brain", designed and built by Josef Kates at Rogers Majestic, was displayed at the Canadian National Exhibition in 1950, while Nimrod, conceived by John Bennett at Ferranti and built by Raymond Stuart-Williams, was displayed at the Festival of Britain and the Berlin Industrial Show in 1951. Neither game incorporated a cathode ray tube (CRT) display. Before these, automated games like the simple chess simulator El Ajedrecista (1914) and Nimrod's predecessor "Nimatron" (1940) had been created as electro-mechanical devices.
