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.
Magnavox Odyssey series
The Magnavox Odyssey, released by Magnavox in 1972, is the world's first home video game console. Designed by Ralph Baer and first demonstrated on May 24 1972, it was sold by Magnavox and affiliates through 1975. The Odyssey uses a type of removable printed circuit board card that inserts into a slot similar to a cartridge slot, allowing the player to select the unit's various games.
