Activision announced that its Call of Duty franchise has officially generated over three billion dollars in worldwide retail sales, making it one of the biggest and most successful video game franchises in history.

Bobby Kotick, CEO of Activision Blizzard: Call Of Duty has become 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.”

Well I think we all know what led to this historic claim–cough, Modern Warfare 2, cough.
