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.
Alan Kotok
Kotok was a precocious child who skipped two grades before college. At MIT he became a member of the Tech Model Railroad Club, and after enrolling in MIT's first freshman programming class, he helped develop some of the earliest computer software including a digital audio program and what is sometimes called the first video game ("Spacewar!"). Together with his teacher John McCarthy and other classmates, he was part of the team that wrote the Kotok-McCarthy program which took part in the first chess match between computers.
