Activision: MW2 sold 4.7m in one day
And that's just in the UK and US.
Activision has calculated that Modern Warfare 2 sold approximately 4.7m copies across the UK and US in just one day.
That record-breaking number means the publisher made approximately $310 or £188m in 24 hours.
Activision boss Mike Griffith called the Call of Duty franchise a "cultural phenomenon", and said the "shattering" of records was due to a MW2 being "compelling, cinematic and uniquely engaging".
"Modern Warfare 2 has taken interactive experience to unprecedented heights setting a new standard for entertainment," he reckoned.
The totals are a result of "internal Activision estimates", and are close to what analyst Michael Pachter predicted. Whether that casts a shadow on the GTAIV-shattering UK sales that Chart-Track counted we don't know.
Modern Warfare 2 was released on Tuesday 10th November amidst a swarm of consumer and media hype.
