According to industry insiders, Google has been spending big sums on TV, magazine and newspaper ads to promote new services, including its Google+ social network and Chrome Web browser. Google's ad-spending as a percentage of revenue is now similar to those of rivals Apple, Microsoft, and Yahoo. According to Kantar Media, Google spent about $213 million to advertise its own products in the U.S. in 2011, nearly quadrupling the $56 million spent in 2010.
