Facebook reports 138% rise in profits

acebook 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.
But Facebook's rapid expansion has resulted in a sharp rise in costs.
Expenses were $1.52bn in the second quarter up 22% from 2013.
"We had a good second quarter," said Facebook founder and chief executive Mark Zuckerberg in a statement accompanying the results.http://www.bbc.com/news/business-28455038
