By comparison, the current worldwide box-office record-holder is Harry Potter and the Half-Blood Prince, which earned $394 million in its first five days. The Dark Knight holds the US box-office record with $203.8 million. The title has even successfully trounced Grand Theft Auto IV, which pulled in $500 million over the first five days of sales.
If the scale of Modern Warfare 2's launch has yet to set in, here are a few more numbers. According to Activision Blizzard (MW2's publisher), the game logged more than 5.2 million multiplayer hours via Xbox Live on the first day alone. In fact, on November 10, 2.2 million unique gamers played on Xbox Live, setting a new one-day record for the platform -- and 995,462 of those people were playing MW2.
