PARIS, France – October 7, 2010 – Blizzard Entertainment, Inc. announced today that the subscriber base for World of Warcraft®, its award-winning massively multiplayer online role-playing game (MMORPG), now exceeds 12 million players worldwide. This milestone was reached in the wake of the mainland Chinese launch of World of Warcraft’s second expansion, Wrath of the Lich King®, and also as global anticipation continues to mount for the December 7 release of the game's third expansion, Cataclysm™.

“The support and enthusiasm that gamers across the world continue to show for World of Warcraft reaffirms our belief that it offers one of the best entertainment values available today,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “We are as committed as ever to taking the game to new heights, and we look forward to demonstrating that with Cataclysm in December.”

World of Warcraft subscribers include individuals who have paid a subscription fee or have an active prepaid card to play World of Warcraft, as well as those who have purchased the game and are within their free month of access. Internet Game Room players who have accessed the game over the last thirty days are also counted as subscribers. The above definition excludes all players under free promotional subscriptions, expired or cancelled subscriptions, and expired prepaid cards. Subscribers in licensees’ territories are defined along the same rules.
