Blizzard today announced it has more than one million paying World of Warcraft subscribers in North America, bringing the total number of subscribers for the game to over 4 million. Just last month Blizzard announced a total of 3.5 million subscribers so they continue to add new players at a rapid pace.

"It's very rewarding to see so many new and returning players logging in to play World of Warcraft daily," said Mike Morhaime, president and cofounder of Blizzard Entertainment. "With the continued support of our retail partners, World of Warcraft has reached more than one million paying customers in North America well before its one-year anniversary in November. We would like to express our appreciation to both the players and our retail and license partners for helping us make World of Warcraft one of the most popular online games in the world."
