NEW YORK (

TheStreet

) -

Activision

(ATVI) - Get Report

announced Tuesday that worldwide sales of its

Call of Duty: Black Ops

title had surpassed $1 billion since its November release.

The milestone is particularly significant, as theatrical blockbuster

Avatar

is the only other entertainment title to reach the $1 billion revenue mark within a similar time frame, according to Activision CEO Bobby Kotick.

Black Ops

generated more than $650 million in its first five days, beating the $550 million record set by its predecessor

Call of Duty: Modern Warfare 2

.

Black Ops

is a first-person shooter video game that takes place during the Cold War.

Earlier this month, Activision's

World of Warcraft: Cataclysm

became

the fastest-selling PC game of all time

, selling 3.3 million copies in its first 24 hours of release.

Shares of Activision jumped 2% in afternoon trading to $12.47.
