Bobby Kotick bought the company. Kotick instituted a large restructuring to reduce debt, including renaming the company back to Activision and moving it to Santa Monica, California. By 1997 the company was profitable again. Kotick spent the next decade expanding Activision's products through acquisitions of around 25 studios. This resulted in Activision publishing several successful series of games, including Tony Hawk's, Call of Duty, and Guitar Hero. However, by around 2006, the popularity of massively multiplayer online (MMO) games started to grow. Such games provide a constant revenue stream to their publishers, rather than only a single purchase, making them a more valuable proposition. None of Activision's subsidiaries had an MMO or the capability to make one quickly. Activision was also facing tougher competition from companies like Electronic Arts, as well as slowdowns in sales of their key game series. Around 2006, Kotick reached out to Jean-Bernard Lévy, the CEO of the French media conglomerate Vivendi. Vivendi at that time had the games division Vivendi Games, a holding company principally for Sierra Entertainment and Blizzard Entertainment. Kotick wanted to get access to Blizzard's World of Warcraft, a successful MMO, and suggested a means to acquire this to Lévy. Lévy instead offered that he would be willing to merge Vivendi Games with Activision, but only if Vivendi kept majority control of the merged company. According to those close to Kotick, Kotick was concerned about this offer as it would force him to cede control of Activision. However, after talking to Blizzard's CEO Mike Morhaime, Kotick recognized that Vivendi would be able to give them inroads into the growing video game market in China. Kotick proposed the merger to Activision's board, which agreed to it in December 2007. The new company was to be named Activision Blizzard and would retain its central headquarters in California. Bobby Kotick of Activision was announced as the new president and CEO, while René Penisson of Vivendi was appointed chairman. The European Commission permitted the merger to take place in April 2008, approving that there weren't any EU antitrust issues in the merger deal. On July 8, 2008, Activision announced that stockholders had agreed to merge, and the deal closed the next day for an estimated transaction amount of US$18.9 billion. Vivendi was the majority shareholder, with a 52% stake in the company. The rest of the shares were held by institutional and private investors, and were
