While Activision was highly successful with its range of developers and successful series, Kotick was concerned that they did not have a title for the growing massively multiplayer online market, which presented the opportunity for continued revenues from subscription models and microtransactions instead of the revenue from a single sale. Around 2006, Kotick contacted Jean-Bernard Lévy, the new CEO of Vivendi, a French media conglomerate. Vivendi had a games division, Vivendi Games, that was struggling to be viable at the time, but its principle feature was that it owned Blizzard Entertainment and its highly successful "World of Warcraft" game, which was drawing in a year in subscription fees. Vivendi Games also owned Sierra Entertainment.
