Early history of video games
The history of video games spans a period of time between the invention of the first electronic games and today, covering a long period of invention and changes. Video gaming reached mainstream popularity in the 1970s and 1980s, when arcade video games, gaming consoles and home computer games were introduced to the general public. Since then, video gaming has become a popular form of entertainment and a part of modern culture in most parts of the world. The early history of video games, therefore, covers the period of time between the first interactive electronic game with an electronic display in 1947, the first true video games in the early 1950s, and the rise of early arcade video games in the 1970s ("Pong" and the beginning of the first generation of video game consoles with the Magnavox Odyssey, both in 1972). During this time there were a wide range of devices and inventions corresponding with large advances in computing technology, and the actual first video game is dependent on the definition of "video game" used.

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.
