If you ever doubted that the merger between Activision and Vivendi Games was all about World of Warcraft, this should set you straight. A games industry analyst has reckoned that the Blizzard MMO accounted for half of the publishing giant's earnings in the last fiscal year.
According to Edge, Arvind Bathia of Stern Agee has estimated that WOW subscriptions and sales added up to earnings per share of 30 out of 60 cents, or USD 400 million, in the company's fiscal year which ended in December.
Considering the other half of Activision Blizzard boasts runaway successes like Guitar Hero and Call of Duty, that's no mean feat. WOW's subscriber base rose to 11.5 million last December, in the wake of new expansion Wrath of the Lich King.
