"For the foreseeable future, the majority of our growth will be through ads," Google chief executive Eric E. Schmidt said in an interview. The worldwide ad market is $600 billion to $800 billion, and online ads still make up only 5 to 10 percent of that, which means that Google and other online companies could still make massive gains.
"We have unmatched reach in audience, and that's why [advertisers] come to Google."
