Video game development
The history of game making begins with the development of the first video games, although which video game is the first depends on the definition of "video game". The first games created had little entertainment value, and their development focus was separate from user experience—in fact, these games required mainframe computers to play them. "OXO", written by Alexander S. Douglas in 1952, was the first computer game to use a digital display. In 1958, a game called "Tennis for Two", which displayed its output on an oscilloscope, was made by Willy Higinbotham, a physicist working at the Brookhaven National Laboratory. In 1961, a mainframe computer game called "Spacewar!" was developed by a group of Massachusetts Institute of Technology students led by Steve Russell.
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.
