Infinity Ward

Infinity Ward, Inc. is an American video game developer best known for creating the *Call of Duty* series. Founded in 2002 by Vince Zampella, Grant Collier, and Jason West, the studio was formed by 22 former colleagues from 2015, Inc., who had previously worked on *Medal of Honor: Allied Assault*. Activision initially invested in the company by acquiring 30 percent of its shares before fully purchasing it. Infinity Ward's debut title, the World War II-themed *Call of Duty*, was released for PC in 2003, and Activision acquired the remaining shares the following day. The studio went on to develop several major entries in the *Call of Duty* franchise, including *Call of Duty 2*, *Call of Duty 4: Modern Warfare*, and its sequels, as well as *Call of Duty: Ghosts*, *Call of Duty: Infinite Warfare*, and the *Modern Warfare* reboot series.
