Activision is now the world's largest video game maker according to the LA Times. The company's rise above Electronics Arts as the top publisher is a result of Guitar Hero's massive success in addition to Tony Hawk, Call of Duty, and Spider-Man games.

The achievement could be short-lived, however, as EA readies several heavy hitting games to directly compete with Activisions's lucrative batch of titles. Games like Madden, Medal of Honor: Airborne, Skate, and Rock Band will go head-to-head against games like Call of Duty, Tony Hawk, and Guitar Hero III with the former games possibly pushing EA back on top by the end of the year.

Activision claims they're not worried, though. "We're well situated to win," a company representative confidently said noting the several awards its games have won over the years most recently including Call of Duty 4 at this year's E3.
