Call of Duty: Modern Warfare 2 has earned more than $1 billion since it was released in November.

“Call of Duty: Modern Warfare 2 has exceeded our expectations and shattered theatrical box office and video game records,” said Robert Kotick, CEO of Activision Blizzard. “There are only a handful of entertainment properties that have ever reached the $1 billion mark, which illustrates the power of the Call of Duty franchise and mass appeal of this game.”
