World of Warcraft Bigger Than New York City

Blizzard's massively multiplayer online role-playing game World of Warcraft now counts a subscriber base of over 9 million, more than the population of New York City, the company announced Tuesday. The virtual world has become so popular that it has remained a top-seller since its debut in November 2004.

The "Burning Crusade" expansion for World of Warcraft sold 3.5 million copies in its first month, and is preparing to bring the add-on to mainland China where it expects to add even more subscribers. World of Warcraft is offered in seven languages and is played around the world in North America, Europe, Australia and Asia.
