Early history of video games
Throughout the rest of the 1960s, digital computer games were created by increasingly numerous programmers and sometimes sold commercially in catalogs. As the audience for video games expanded to more than a few dozen research institutions with the falling cost of computers, and programming languages that would run on multiple types of computers were created, a wider variety of games began to be developed. Video games transitioned into a new era in the early 1970s with the launch of the commercial video game industry in 1971 with the display of the coin-operated arcade game "Galaxy Game" and the release of the first arcade video game "Computer Space", and then in 1972 with the release of the immensely successful arcade game "Pong" and the first home video game console, the Magnavox Odyssey, which launched the first generation of video game consoles.
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.
