Activision Blizzard announced that Infinity Ward's Call of Duty: Modern Warfare 2 has topped the $1 billion mark in retail sales worldwide since its launch in November, according to internal Activision estimates.
Activision also says that in its first five days alone, Call of Duty: Modern Warfare 2 sold an estimated $550 million worldwide, outpacing five-day worldwide theatrical box office gross figures for such films as Avatar, Harry Potter and the Half-Blood Prince and The Dark Night.
This sales record for Call of Duty: Modern Warfare 2 is also pretty astonishing as it is rated Mature. The movie Avatar for instance had to cut some alien sex scenes to get a PG-13 rating for cinema release.
Call of Duty: Modern Warfare 2 for PS3 and Xbox 360 is on sale on Amazon for $45 right now.
