Activision's Call of Duty: Modern Warfare 2 has surpassed $1 billion in retail sales worldwide since launch in November.
In its first five days on sale the game made an estimated $550 million worldwide, out-pacing theatrical gross figures of movies such as The Dark Knight, Avatar and Harry Potter and the Half-Blood Prince, according to Activision.
"Call of Duty: Modern Warfare 2 has exceeded our expectations and shattered theatrical box office and videogame records," offered 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."
