The social network now has over 1 billion active mobile users, according to the numbers provided by Mark Zuckerberg in a call with investors following Facebook’s acquisition of Oculus VR, a start-up specializing in virtual reality. In December 2013, Facebook revealed that it already had 945 million active mobile users. Zuckerberg also announced that Instagram, which is owned by Facebook, has just passed the benchmark of 200 million active users, compared to 150 million three months ago.
