Mobile now makes up 23pc of Facebook ad revenue
Mark Zuckerberg, founder, Facebook
Fourth quarter revenue at Facebook climbed 40pc to reach $1.59bn while earnings fell by $360m to $64m as it strives to tap into the mobile opportunity.
Facebook now has 1.06 billion users, up 25pc from a year earlier. About 680 million of them access Facebook using a mobile device each month, but the company only started showing mobile ads about nine months ago.
Facebook said it generated 23pc, or $306m, of advertising revenue from mobile. The overall results were better than analysts anticipated, but they had expected mobile ad revenue to grow by 25pc.
