Noted in the press release
this evening announcing the split of Activision-Blizzard from Vivendi is the fact that World of Warcraft ended the last quarter at 7.7 million subscribers, down from 8.3 million in March
For the quarter, Activision Blizzard was the #1 independent publisher in North America and Europe combined, including accessory packs and figures, with the #1 and #2 best-selling titles year-to-date– Skylanders Giants™ and Call of Duty: Black Ops II.¹ Additionally, Blizzard Entertainment's World of Warcraft® remained the world's #1 subscription-based MMORPG, ending the quarter with approximately 7.7 million subscribers.
Subscriber Definition: 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.
It should be noted that these numbers are world-wide, and they are not broken out into the North American / European / Asian split that people often like to talk about.
