Activision revealed that Call of Duty: Black Ops 2 overshot the $1 billion mark in retail sales across the globe, according to Chart-Track. The game launched on November 13, 2012. In comparison, Modern Warfare 3 reached $1 billion in retail sales in 16 days.

Also, it's worth noting that the box office record set for feature films in 2009 by "Avatar" was $1 billion in 17 days.

"The release of Call of Duty has been one of the most significant entertainment events of each of the last six years," said Bobby Kotick, CEO of Activision Blizzard. "Since Call of Duty was launched, cumulative franchise revenues from players around the world are greater than current worldwide box office receipts to date for the top-10 grossing films of 2012 combined. Life-to-date sales for the Call of Duty franchise have exceeded worldwide theatrical box office receipts for 'Harry Potter' and 'Star Wars,' the two most successful movie franchises of all time."

Since the game's launch, more than 150 million hours have been logged online playing Call of Duty: Black Ops II on Xbox LIVE and PlayStation Network.

I think they should launch three Call of Duty games next year. And then they should increase that number, until we finally enter an age where one Call of Duty game launches every month... Nay, make that every day. Wouldn't that be a spectacular world to live in?
