Facebook: Mobile ad revenue jumps from zero to 23%

In a statement announcing the company's fourth-quarter results, Facebook says there are now 1.06 billion active Facebook users across the globe. More than half (618 million) visit daily - a YoY rise of 57%.

Also announced was that 157 million monthly active users only access Facebook from their mobile device, up from just 58 million mobile-only users in Q4 2011.

Facebook CEO, Mark Zuckerberg, says the social network has now become a "mobile company".

In Q4 2012, mobile ads accounted for a significant 23% of ad revenue, a big jump from the third quarter when it was 14%.

The social network's finance chief, David Ebersman, said Facebook had "basically doubled" mobile ad revenue from the third quarter to the fourth quarter.

"Two quarters ago we really had no mobile revenue," Ebersman told Reuters. "In the course of a pretty short period of time, we've dramatically ramped up our ability to monetize mobile."

Facebook reported a net income of $64 million on sales of $1.58 billion for Q4 2012. Revenue rose 40% from a year ago, but profit fell 78% as the company incurred charges related to employee stock options.
