Google's mobile business is on an $8 billion revenue run rate, CEO Larry Page said during the company's earnings call.
"That's quite a business," he said.
Page didn't break out where the revenue is coming from, only saying a part of the growth is due to "users paying for content and apps in Google Play."
When asked specifically about the mobile advertising revenue, SVP and CFO Patrick Pichette said, "clearly we don't break down the categories. Ads continue to be the bulk of [the $8 billion], the vast majority of it."
