Facebook profits surge on mobile ads
24 July 2014 Last updated at 02:28 BST
Facebook has announced a 138% rise in net income for the second quarter to $791m (£464m).
Revenue from advertising, which makes up most of Facebook's income, was $2.68bn, up 67% compared with the second quarter of 2013.
Adverts on mobile devices now account for 62% of advertising revenue, which is a spectacular rise as mobile ads accounted for almost nothing in 2012.
Analyst Tim Charlton gave his reaction to Facebook's latest set of results.
