Blizzard Entertainment certainly knows how to promote a product. The company announced that it sold 2.8 million copies of Wrath of the Lich King within the first 24 hours, beating the previous record in Jan. 2007, when they sold 2.4 million copies of The Burning Crusade. As we previously let you know, Blizzard opened doors at midnight at over 15,000 stores worldwide. Before the launch there were more than 11 million gamers. We expect that the amount will increase with the new expansion sales.
