Achieved as the social network's mobile monthly actives reach 819m.
Facebook embarked on a mission to monetise its mobile services last year, and it's a move that's paid off judging from its second quarter figures – ending June 30th 2013.
Overall revenue for Q2 reached $1.81 billion at a 53 per cent year-on-year increase from $1.18bn.
Advertising, of course, brought home the bulk of the figures at $1.6 billion – equivalent to 88 per cent of total revenue – up 61 per cent year-on-year, with mobile accounting for 41 per cent of all ad revs.
The figures are really impressive, given mobile ad revs accounted for just 14 per cent of all ad revenue back in Q3 2012 – the period when mobile ads were first introduced – despite analysts predicting mobile to secure a third.
Mark Zuckerberg, founder and CEO, Facebook, said: "We've made good progress growing our community, deepening engagement and delivering strong financial results, especially on mobile.
"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."
Meanwhile, further evidence to support the mobile boom comes as mobile monthly active users climbed 51 per cent year-on-year to reach 819 million, while daily actives reached 469m.
Comparatively, overall monthly actives were up 21 per cent year-on-year to reach 1.15 billion, while daily actives grew 27 per cent to hit 699m.
The company is currently trialling pushing mobile ads to user notifications to build revenue opportunities, and noted the success of campaigns from Unilever, Pimm's, and Pepsi.
Other moves in the business during Q2 saw Facebook introduce video to Instagram, which encouraged users to upload five million videos in the first 24 hours. Users can now also embed content into web pages.
The social network has also passed the 100 million downloads milestone for its feature phone app, crossed one million active advertisers, launched Twitter-like Verified Pages and hashtags.
