Cosmi Corporation was established in 1982, founded by George Johnson. The company published titles for many personal computer systems such as the Atari 8-bit family, Commodore 64 and IBM PC. This included many games, such as Forbidden Forest, The President Is Missing, or the very popular Aztec Challenge. It also published utility software including a database, word processor, spreadsheet, street maps, vacation planners, a 3D World Atlas, and other tools.

By Fall of 2012, Cosmi merged with ValuSoft to create ValuSoft Cosmi.
