NewFacebook revenue results smash expectations as mobile ad sales surge; shares jump in US after-hours trade.

Facebook’s quarterly revenue rose more than 50 per cent, handily beating Wall Street expectations as its wildly popular mobile app and a push into live video lured new advertisers and encouraged existing ones to boost spending.
Facebook also announced a proposal to create a new class of non-voting shares, which would be given as a dividend to existing shareholders.
The company’s shares rose 9.5 per cent in after-hours trading on Wednesday.
The dividend of non-voting shares would allow Chief Executive Mark Zuckerberg, who plans to give away the majority of his wealth, to sell part of his stake in Facebook without giving up any of his voting control. That way, Facebook, said Zuckerberg, could remain in an “active leadership role”.
Mobile ad revenue accounted for about 82 per cent of total ad revenue in the first quarter ended March 31, compared with about 73 per cent a year earlier.
Facebook said it had 1.65 billion monthly active users as of March 31, up from 1.44 billion a year earlier.
