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 online games
The first video and computer games, such as NIMROD (1951), OXO (1952), and Spacewar! (1962), were for one or two players sitting at a single computer which was being used only to play the game. Later in the 1960s, computers began to support time-sharing, which allowed multiple users to share use of a computer simultaneously. Systems of computer terminals were created allowing users to operate the computer from a different room than where the computer was housed. Soon after, Modem links further expanded this range so that users did not have to be in the same building as the computer; terminals could connect to their host computers via dial-up or leased telephone lines. With the increased remote access, "host based" games were created, in which users on remote systems connected to a central computer to play single-player, and soon after, multiplayer games.
