One day after the latest installment in the Call Of Duty franchise was released, Activision Blizzard announced today that the first-person shooter video game has surpassed $1 billion in global sell-in sales. Impressive as that may sound, it’s not a record yet, and it hasn’t taken out Grand Theft Auto V either. Unlike last year’s Call Of Duty: Black Ops II, which sold $500M on its first day last November, the $1 billion represents the copies shipped to retailers not actual point-of-purchase sales — Activision Blizzard hasn’t released that figure yet. Previously the fastest-selling video game ever, Back Ops II was thrashed by Grand Theft Auto V when the Take Two Interactive game hit $800 million in sales in one day after its September 17 release. Leaping ahead of the box office of Hollywood blockbusters Man Of Steel and Despicable Me 2, GTA V topped $1 billion in a record making three days whereas it took Black Ops II just over two weeks to get to that number back in fall 2012. The 10thgame in the franchise, the dystopian story of Call Of Duty: Ghosts was put together in part by Oscar-wining scribe Stephen Gaghan, who worked on the multi-level story. Unlike GTA V, which was initially available on just PlayStation 3 and Xbox 360, Ghosts debuted on Xbox 360, PlayStation 3, Nintendo Wii U and Windows PC. The game is also set to be the launch title for the PlayStation 4 and Xbox One later this month.
