Stephen Holmes - Electronic Arts

I'll go with Electronic Arts, the video game developer that owns BioWare and Mythic Entertainment (among other things). They've got EA Sports too - that's a pretty big deal. The most interesting part about them, though, is their recent initiative to buy out independent mobile game developers and try to corner the market for mobile devices. Because of their casual style and extremely cheap prices, mobile games (for the iPhone, etc) are starting to concern PC and console game manufacturers.
