15 days to reach the milestone.
Call of Duty: Black Ops 2 took just 15 days to reach the $1 billion mark in worldwide retail sales, according to Chart-Track consumer sell-through information and internal company estimates.
Last year's Modern Warfare 3 reached the same mark in 16 days, whilst Avatar set the box office record back in 2009 by reaching $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 launch more than 150 million hours have been logged online playing Black Ops 2 on Xbox LIVE and PSN.
CEO of Activision Publishing Eric Hirshberg added that fresh ideas are needed in order to keep fans coming back for more.
"In order for Call of Duty to remain the entertainment juggernaut that it is, and keep our fans coming back for more, we need to continue to bring fresh ideas and new innovations to the table every time, while always staying true to what people fell in love with in the first place," said Hirshberg. "That's what we did with Call of Duty: Black Ops II, and that's what we intend to keep on doing. This is an incredible milestone for an incredible franchise, and I want to thank every passionate, talented, committed person on our team who made it happen."
