Wizardry: Proving Grounds of the Mad Overlord is the first game in the Wizardry series of role-playing video games. It was developed by Andrew Greenberg and Robert Woodhead. In 1980, Norman Sirotek formed Sir-Tech Software, Inc. and launched a beta version of the product at the 1980 Boston Computer Convention. The final version of the game was released in 1981.

PLATO, also known as Project Plato and Project PLATO, was the first generalized computer-assisted instruction system. Starting in 1960, it ran on the University of Illinois's ILLIAC I computer. By the late 1970s, it supported several thousand graphics terminals distributed worldwide, running on nearly a dozen different networked mainframe computers. Many modern concepts in multi-user computing were first developed on PLATO, including forums, message boards, online testing, email, chat rooms, picture languages, instant messaging, remote screen sharing, and multiplayer video games.
