The NPD has confirmed that Call of Duty: Black Ops is now the best selling game in the history of the U.S. The game has passed Wii Play, having sold over 13.7 million units.

Call of Duty: Black Ops has been the top selling game since its release in November and that has continued into the month of February. Helping the game reach the sales mark that Call of Duty: Modern Warfare 2 did not is the fact that it release on DS and Wii as well as PS3, PC and Xbox 360.
