Majority of Facebook’s 900M users are mobile [500M]

According to a filing with the U.S. Securities and Exchange Commission this afternoon, the social network giant Facebook hit 500 million mobile users (via Business Insider). Furthermore, the IPO-destined company also announced that it has 900 million total users, 500 million of which return to use the website on a daily basis.

Facebook is currently available on every major mobile platform through an app. Facebook also has a nicely done HTML 5 mobile website, so those without the app can still have access. With so many people using smartphones these days, it is obvious why so many people are accessing the social network through their mobile phone.

As for the company’s quarterly revenue, it climbed 45 percent year-over-year to a whopping $1 billion. As for net income, Facebook racked $204 million.

The SEC filing also shed some more information on the recent Instagram acquisition. If the proposed $1 billion acquisition fails to go through, Facebook will actually end up owing Instagram $200 million.

Apple is rumored to incorporate Facebook into iOS; similar to the way Twitter is integrated. With so many people now using the social network, I think it would be a smart move.
