Colossal Modern Warfare 2 sales have nudged Activision's Call of Duty franchise over the $3 billion revenue mark.
The publisher announced today that the six titles in the series have combined to sell over 55 million units around the world.
Activision boss Bobby Kotick said this data - based on NPD, GfK Chart-Track and international data - has made Call of Duty one of the "greatest entertainment franchises of all time".
"If you consider the number of hours our audiences are engaged in playing Call of Duty games, it is likely to be one of the most viewed of all entertainment experiences in modern history," he added.
Modern Warfare 2 was released for PC, PS3 and Xbox 360 on 10th November. The game sold in incredible amounts during its opening-week and still tops the UK all-formats chart today, swatting away very strong competition from Assassin's Creed II.
