ICOM Simulations was a video game developer that was founded on March 4, 1981 in Wheeling, Illinois. The company was acquired by Viacom New Media in 1993, and was closed in 1997. They developed several adventure games using the MacVenture engine.
In January 2012, former ICOM developer Dave Marsh obtained the rights to most of ICOM's games. On March 5, 2012, Dave Marsh and fellow ex-ICOM developer Karl Roelofs formed Zojoi to release the ICOM games, both in their original format and as enhanced remakes for modern machines.
