Google just announced its fourth quarter 2012 earnings. The firm reported $14.42 billion in revenue for the quarter, up 36 percent over the same quarter last year and up 8 percent since the third quarter of 2012.

"We ended 2012 with a strong quarter," Google CEO Larry Page said. "Revenues were up 36% year-on-year, and 8% quarter-on-quarter. And we hit $50 billion in revenues for the first time last year – not a bad achievement in just a decade and a half. In today's multi-screen world we face tremendous opportunities as a technology company focused on user benefit. It's an incredibly exciting time to be at Google."

Motorola Mobility's revenues totaled $1.51 billion, although the firm also said that there was a $353 million Motorola Mobility operating loss during the quarter.
