Microsoft
Microsoft's got a finger in just about every pie, including the video game software played on its Xbox and Xbox 360, as well as PCs running the Windows operating system. Microsoft Game Studios, a division of the computing behemoth, oversees Xbox and PC gaming operations. Popular titles include the Age of Empires and Age of Mythology series, Halo (coming soon to movie theaters near you, directed by über-geek Peter Jackson), Zoo Tycoon, and Project Gotham Racing. The division also offers Xbox Live, currently the largest online gaming subscription service.

The company generates revenue through ads that are targeted by keywords. Google also sells ads across a network of more than 200,000 affiliated Web sites. Founders Sergey Brin and Larry Page each have nearly 30% voting control of the company.
