Call of Duty is one of the most culturally significant video game franchises of the 21st century. Since the first game was released for PC in 2003, the first-person shooter has sold over 250 million copies across a range of platforms, along with merchandise ranging from toys and comic books to a special edition Jeep Wrangler. Top players can compete for millions in prize money in tournaments sanctioned by the Call of Duty World League.
