Activision announced today that Call of Duty: Modern Warfare 2 sales hit the $1 Billion (US) mark in worldwide sales. In a statement made by Activision/Blizzard CEO Bobby Kotick,  “Call of Duty: Modern Warfare 2 has exceeded our expectations and shattered theatrical box office and video game records. There are only a handful of entertainment properties that have ever reached the $1 billion mark, which illustrates the power of the Call of Duty franchise and mass appeal of this game.”

Modern Warfare 2’s release on November 10, 2009 was hailed as the “biggest launch in history across all forms of entertainment” with estimated sales of $550 million US in the first five days alone.

Multiple DLC packs are in store for the billion dollar game later this spring. Microsoft’s Robbie Bach at the CES stated, “”This spring, the first content packs for Call of Duty: Modern Warfare 2 from Activision will be available, again, exclusively first on Xbox 360.”
