With more than 55 million units sold, Activision has recently announced that its Call of Duty franchise has hit over $3 billion in retail sales worldwide. The latest title in the franchise, Infinity Ward’s Call of Duty: Modern Warfare 2, recently shattered box office and video game records with a worldwide estimated five-day sale through of approximately $550 million, establishing the game as the biggest entertainment launch in history.

“Call Of Duty has become one of the greatest entertainment franchises of all time,” said Bobby Kotick, CEO of Activision Blizzard, Inc. “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.”

For comparison’s sake, the largest selling franchise of all time is Nintendo’s Mario, with an estimated 222 million units sold. Could he possibly lose his throne in the near future to…a shooter?
