I’d almost be willing to bet a million dollars that you have a Facebook account. Of course you do, because Facebook revealed in its second quarter earnings today just how many people use Facebook every day. According to the report, as of June 30th, it had over 1.7 billion monthly active users (MAUs) – an increase of 15% year-over-year – and 1.57 billion mobile monthly active users.The figures don’t stop there. Facebook’s title as the world’s largest social network still stands as it is the first time the social network giant has surpassed 1 billion mobile daily active users (DAUs). What’s even more mind-blowing is that the number of mobile-only monthly active users is also about to surpass the 1 billion milestone. To be clear, Facebook defines mobile-only MAUs as such: Mobile-only MAUs are defined as users who accessed Facebook solely through mobile apps or mobile versions of our website, or used our Messenger app, in the last 30 days of the given quarter. The number of mobile-only MAUs do not include Instagram users unless they would otherwise qualify as such users based on their other activities on Facebook.
