FILE - In this July 8, 2010 file photo, Google co-founder Larry Page arrives to a morning session at the annual Allen & Co. media summit in Sun Valley, Idaho.  When he replaced his mentor Eric Schmidt as Google's CEO, Larry Page knew he had to be more aggressive in countering the threat posed by Facebook. For years, Facebook has been stockpiling valuable information about people's social circles and interests. Google has responded by creating a social network of its own, Google Plus. That social networking crusade dominated the first year of Page's return as CEO and is still reshaping Google Inc. (AP Photo/Nati Harnik, File)
