7. Eric Schmidt, Google
Nearly a year ago came word that Eric Schmidt would pass the Google CEO torch to Google co-founder Larry Page in April. Schmidt had been CEO of Google since August 2001 and presided over its ascent to one of the premier technology companies in the world, so the move was a major changing of the guard by any definition, even with Page getting back into the operational driver's seat of the company he and Sergey Brin founded all those years ago now. Schmidt remains Google's executive chairman.
