There are a few properties in the entertainment market that are expected to have huge releases. That includes the newest Call of Duty game, as well as the newest installment to the Gran Turismo franchise. Both of those games managed to sell a ridiculous amount of copies, with Call of Duty: Black Ops destroying entertainment records on its own. One other franchise is just as anticipated, and when a new game launches, everyone knows that huge numbers are going to be racked up. World of Warcraft: Cataclysm didn't disappoint.
According to developer Blizzard Entertainment, the latest installment/expansion for the World of Warcraft series managed to sell 3.3 million copies in its first 24 hours of being on sale. That means that it broke the record for "fastest selling PC game, ever." There's a bit of irony in the fact that Blizzard Entertainment actually beat out the previous World of Warcraft title, Wrath of the Lich King, which sold 2.8 million copies in its first 24 hours of being on sale, in 2008.
