Andy Rubin
Senior Vice President, Mobile, Google
As smartphones and tablets become more prevalent, Rubin's role arguably becomes that much more important for Google. Rubin is the founder of Android, the rapidly growing mobile operating system, which stands in stark relief to the heavily-controlled approach of Apple's iOS. It's also giving Cupertino a serious run for its money. More than 850,000 Android devices are now activated on a daily basis, and as of last February, 48% of all smartphones in the U.S. ran the operating system.
