Atari pioneered the arcade video game and helped launch the video game revolution with the introduction of Pong (1972), the Home Pong console (1975), and the Atari 2600 (1977) during the 1970s. Initially as Atari Inc. (1972–1984) and later as Atari Games (1984–1999), the company produced iconic arcade video games and pinball machines such as Pong, Breakout (1976), Asteroids (1979), Superman pinball (1979), Missile Command (1981), Star Wars (1983), Gauntlet (1985), and Primal Rage (1994). The collection encompasses a wide array of historical materials, including more than 3,000 pieces of original concept and final arcade cabinet artwork, hand-drawn assembly design sketches, storyboards, photographs, and print advertising proofs; hundreds of original art kits and production films for Atari arcade video game cabinets; nearly 2,800 videos of game demos, television commercials, industry show presentations, focus groups, and company celebrations; arcade game source code; promotional materials; and an unreleased Maze Invaders arcade video game—one of only two units known to exist. Also included in the Atari Coin-Op Division Corporate Records collection are dozens of binders chronicling the production of virtually every Atari coin-operated game from 1972 to 1999; extensive corporate records documenting game brainstorming sessions, industry and market research, and player game evaluations; and company correspondence, newsletters, and technical documentation.
