Mobile advertising delivered 41 per cent of Facebook’s total $1.6bn ad revenue for the second quarter of 2013, prompting CEO Mark Zuckerberg to say that the work done to make Facebook a mobile company is paying off.

The company reported total revenues of $1.8bn for the period up from $1.1bn in the second quarter of last year. Net income hit $333m up from a loss of $157m a year ago.

Monthly active users (MAUs) increased 21 per cent year on year to 1.15 billion, while mobile MAUs increased 51 per cent to 819m with one million Facebook for Every Phone users catered for by an application for limited functionality phones. The firm also surpassed one million active advertisers, driven by significant growth in local businesses.

“The work we’ve done to make mobile the best Facebook experience is showing good results and provides us with a solid foundation for the future,” Zuckerberg said.
