Treyarch

 is a video game developer located in Santa Monica,. It was founded by Peter Akemann and Don Likeness in 1996. Treyarch has developed many games in the Call of Duty series. Activision has owned Treyarch since 2001. In 2005, former employees of Gray Matter Interactive Studios were merged to Treyarch.

History
When Treyarch released Call of Duty 3, it did not fare nearly as well as Infinity Ward's two previous installments, Call of Duty, and Call of Duty 2. After Call of Duty 4: Modern Warfare was released to huge success, Treyarch took some ideas from it and combined it with their own to make Call of Duty: World at War. However, a year later, in 2009, Call of Duty: Modern Warfare 2 broke a record in the gaming industry for most copies sold in 24 hours. In 2010, Treyarch released Call of Duty: Black Ops, and that broke an even bigger record for most entertainment items sold in 24 hours. This record was beaten by Call of Duty: Modern Warfare 3 in 2011. The record was again, broken by Treyarch's Call of Duty: Black Ops II.
