Lionhead Studios Limited was a British video game developer founded in July 1997 by Peter Molyneux, Mark Webley, Tim Rance, and Steve Jackson. The company is best known for the Black & White and Fable series. Lionhead started as a breakaway from developer Bullfrog Productions, which was also founded by Molyneux. Lionhead's first game was Black & White, a god game with elements of artificial life and strategy games. Black & White was published by Electronic Arts in 2001. Lionhead Studios is named after Webley's hamster, which died not long after the naming of the studio, as a result of which the studio was very briefly renamed to Redeye Studios.
