The new Call of Duty: Black Ops II reached $1 billion in sales in 15 days, according to Chart-Track data. That’s one day earlier than last year’s hit version and faster than the highest grossing box office movie of all time, Avatar. The total sales to date for the COD franchise are greater than the current worldwide box office receipts to date for the top 10 grossing films of 2012 combined. In other words, we’re gonna go swim around in our cash now. Buh-bye. [Source Adage]
