Mobile phones represent next frontier for search?
The Chief Executive of Google Eric Schmidt said that the next level for search is "Mobile, mobile, mobile".
Google is the company that generates billions of dollars from online advertising, is racing to bring consumer services like search to the phone.
Its rivals: Yahoo and Microsoft bought voice-recognition technology company Tellme Networks Inc. last month.
"The biggest growth areas are clearly within the mobile space," Schmidt said during a question-and-answer session at the Web 2.0 Expo in San Francisco.
Google controls nearly 50 percent of the U.S. Web search market, is not necessarily a lock to carry over its success on the computer screen to the mobile phone.
"One of the big game changers is mobile," said Tim O'Reilly, founder of O'Reilly Media, a publisher of several popular lines of technology manuals for software programmers.
"Google's dominance in search is dependent on this idea that we sit, typing away at a keyboard to look up information," he said, "but we are in for some huge disruptive upsets."
Last month, Yahoo introduced a new Internet search system to deliver locally relevant answers to mobile phone users' questions in fewer steps than Google. Subjects include news headlines, business listings, local weather and links to other Web sites.
So, the war for conquering the mobile Web world already started.
