Facebook Monthly Mobile Active Users & Ad Revenues, Q3 2012-Q3 2013 [CHART]

Facebook continues to successfully shift to a mobile-oriented platform, with mobile monthly active users (MAUs – 874 million) now comprising almost three-quarters of total MAUs (~1.2 billion), and mobile ad revenue now at 49% of a growing total, according to the company’s latest earnings release. That 49% figure represents a dramatic rise from just 14% of revenues this time last year. Tempering these impressive figures is the now-widely-broadcast disclosure from Facebook that daily use by younger teens decreased between Q2 and Q3.

That confirms survey evidence that Facebook is losing its luster among the younger demographic: a recent survey from Piper Jaffray found that for the first time, it was not named by teens as their “most important” social network, surrendering that distinction to Twitter.
