Facebook now reaches 2 billion monthly users..Youtube next with 1.5 billion for June 2017

A comparison of monthly users for each social media app/site

Two billion makes Facebook the largest social app in terms of logged-in users, above YouTube’s 1.5 billion, WeChat’s 889 million, Twitter’s 328 million and Snapchat’s estimated 255 million (extrapolated from its December 2015 ratio when it had 110 million daily and 170 million monthly users). Beyond YouTube, only Facebook’s other apps have more than 1 billion, including WhatsApp and Facebook Messenger, with 1.2 billion each. Instagram might soon join that club as it recently rocketed past 700 million. @techcrunch
