Eidos Interactive Limited (formerly Domark Limited) was a British video game publisher based in Wimbledon, London. Among its notable franchises were Championship Manager, Deus Ex, Hitman, Thief, and Tomb Raider. Domark was founded by Mark Strachan and Dominic Wheatley in 1984. In 1995, it was acquired by software company Eidos. Ian Livingstone, who held a stake in Domark, became executive chairman of Eidos and held various roles including creative director. Eidos took over U.S. Gold in 1996, which included developer Core Design, and merged its operations including Domark, which created publishing subsidiary Eidos Interactive. The company acquired Crystal Dynamics in 1998, and owned numerous other assets. In 2005, parent Eidos was taken over by games publisher SCi. The combined company, SCi Entertainment Group, which was briefly renamed Eidos, was itself taken over by Square Enix in 2009.
