When Facebook filed for its initial public offering in early 2012, the company named the ongoing transition to mobile as one of the biggest risks to its future success. If the transition to mobile was indeed the biggest challenge in Mark Zuckerberg’s young career as CEO of a billion-dollar company, he managed it admirably well.

Not only does Facebook generate more than half of its revenue on mobile devices, the company also owns three of the hottest apps in the world. First there’s Facebook, which passed one billion mobile users in the first quarter of 2014. Than there’s Instagram, which has more than 200 million users and is immensely popular with tech-savvy Millennials. And finally, there’s Facebook’s most recent acquisition: WhatsApp, which just reported that it passed 500 million active users.

With a mobile line-up like this, Facebook appears to be in a position that all but guarantees sustained success in the mobile landscape. The accompanying chart is courtesy of Statistica.com.
