Facebook now earns most of its money from mobile ads, according to the company's fourth quarter report.
More than half (53 percent) of its $2.6 billion ad revenue came from mobile devices, likely because its daily mobile users have risen 49 million, or 9 percent, according to TechCrunch. Facebook's monthly mobile users have also moved up from 874 million to 945 million (7 percent) and at this rate would hit the 1 billion by March. Facebook has a total of 757 daily users and 1.23 billion monthly users.
Why the boost? Likely from Facebook's latest new mobile apps, including its own ads to install the new app.
