Blizzard Entertainment announced that World of Warcraft: Cataclysm, the third add-on for the Earthly wonder that is WoW, sold through more than 4.7 million copies during the first month of release. According to Blizzard, the game set a new record for monthly PC-game sales.

World of Warcraft: Cataclysm was simultaneously released in the United States, Canada, Mexico, Argentina, Chile, Europe, Russia, Southeast Asia, Australia, and New Zealand on December 7, and became available in Korea and the regions of Taiwan, Hong Kong, and Macau on December 9. With day-one sales topping 3.3 million copies, World of Warcraft: Cataclysm became the fastest-selling PC game of all time, shattering the previous record, which was held by the second World of Warcraft expansion, Wrath of the Lich King®. "We created thousands of new quests, introduced new lands to explore, and extensively revamped the game world for World of Warcraft: Cataclysm, making it our biggest and most ambitious expansion yet," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment.

"We’ve been floored by the community's response so far, and we'd like to thank them for their continued passion and support for World of Warcraft, and for helping Cataclysm reach this incredible milestone."
