Since 2004, the MMO phenomenon that is World of Warcraft has generated over 10.4 million subscribers worldwide. The average WoW subscriber pays over $14.99 a month just to keep up with the daily (level and gear) grind. With one expansion already out, The Burning Crusade, and another one on the way this November 13 with Wrath of the Lich King, how much has Blizzard spent on Azeroth's domain?
According to Activision, Blizzard has spent over $200 million on World of Warcraft since its launch. The amount accounts to every staff personnel--from customer service representatives to the programmers. Kotaku reports that the company's customer service department is the largest among the staff, which shouldn't be a surprise considering there's over 10 million players worldwide.
World of Warcraft, The Burning Crusade and Wrath of the Lich King are both published and developed by Blizzard Entertainment for the PC and Macintosh platforms. The Burning Crusade was released in January 2007.
