Activision has officially received shareholder approval for its merger with Vivendi. The company said over 92 percent of its shareholders greenlighted the merger, and the transaction is expected to officially close tomorrow.

The merger was first announced in December of 2007, but has just now been finalized. Through it, Blizzard and Sierra parent Vivendi becomes a wholly-owned subsidiary of Activision, scoring 295.3 new shares of Activision stock. It'll also buy 62.9 million new shares for a total of $1.7 billion - the result is that Vivendi owns a stake of about 52 percent in its new parent company.

Santa Monica-based Activision's new name will officially be Activision Blizzard, a moniker change also approved by the shareholders today, but it'll continue to trade on the NASDAQ under its same symbol, ATVI.
