Google: Mobile business worth $1B in revenues annually.

"Google said its mobile business--including search, advertising and services--adds $1 billion to its revenue streams annually. And executives emphasized mobile is a growing business.

Jonathan Rosenberg, Google's senior vice president of product management, said during the company's third quarter earnings conference call that mobile is on an annualized run rate of $1 billion. 'The people who are accessing our products and services through their mobile phones are adding $1 billion to our revenue streams,' he said. 'Clearly, this is the future of search on the Internet.' He said mobile search for Google has grown five times over the past several years."
