Bethesda Softworks

Bethesda Softworks LLC is an American video game publisher based in Rockville, Maryland. The company was founded by Christopher Weaver in 1986 as a division of Media Technology Limited, and in 1999 became a subsidiary of ZeniMax Media. In its first fifteen years, it was a video game developer and self-published its titles. In 2001, Bethesda spun off its own in-house development team into Bethesda Game Studios, and Bethesda Softworks became a publisher only. It currently also publishes games by ZeniMax Online Studios, id Software, Arkane Studios, MachineGames, Tango Gameworks and BattleCry Studios.
