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 first user interfaces were plain-text—similar to BBSs— but they operated on large mainframe computers, permitting larger numbers of users to be online at once. By the end of the decade, inline services had fully graphical environments using software specific to each personal computer platform. Popular text-based services included CompuServe, The Source, and GEnie, while platform-specific graphical services included PlayNET and Quantum Link for the Commodore 64, AppleLink for the Apple II and Macintosh, and PC Link for the IBM PC—all of which were run by the company which eventually became America Online—and a competing service, Prodigy. Interactive games were a feature of these services, though until 1987 they used text-based displays, not graphics.
