WoW is one game that's making a lot of people happy. For its 6 million subscribers, it's definitely a source of joy. The guys at Vivendi love this game, too, as it's bringing them a lot of moolah.

But how much, you ask? Well, for the first half of the year (as compared to the same period last year), WoW helped ushered in a 24% increase in the company's gaming division, which is equal to a whopping 296 million euros. Convert that into dollars and you get a cool $377.6 million. As the year progressed, revenues continued to shoot upward. For the second quarter of the year, sales rose by 30% year over year, which is equal to 162 million euros ($206.7 million).

According to Vivendi, Wow is the primary sales driver for the period. Games such as Ice Age 2, 50 Cent: Bulletproof and Crash Tag Team Racing also helped the company do well.

Vivendi games is a conglomerate based in France, with Blizzard Entertainment, Sierra Entertainment, Radical Entertainment, Massive Entertainment, Swordfish Studios and High Moon Studios under its wing.
