Facebook profits nearly tripled to $642 million in the first quarter on a 72 percent surge in revenues, helped by gains in mobile users and mobile advertising, the company reported Wednesday.
Advertising revenues on the huge social network were up 82 percent from a year ago, the company said.
Of that, earnings from mobile ads comprised 59 percent of that, compared with 53 percent in the fourth quarter of last year.
Mobile users continued to dominate the growth picture for the company: daily active users were up 21 percent from a year ago to 802 million, and of them mobile users totaled 609 million, a year-on-year gain of 43 percent.
Monthly active users meanwhile rose to 1.28 billion, one billion of them on mobile.
"Facebook's business is strong and growing, and this quarter was a great start to 2014," Facebook chief executive Mark Zuckerberg said in a statement.
