You know what’s not a bad way to start a new year? How bout announcing that your latest title has sold more than a billion dollars worth. Yes, Modern Warfare 2 has reached that rare milestone among industry developments, and it’s still going strong.

“There are only a handful of entertainment properties that have ever reached the $1 billion mark,” said Activision CEO Bob Kotick, “which illustrates the power of the Call of Duty franchise and mass appeal of this game.” In case you’ve forgotten the baffling sales statistics, more than half of that billion was made in the first five days the game was available. Utterly insane.

In other new, Avatar (the movie, not the game) broke the billion dollar mark not too long ago, putting the two in a race to beat out Titanic’s $1.8 billion gross and Guitar Hero III‘s $2 billion.
