How Facebook Messenger clawed its way to 1 billion users

Facebook’s gamble of forcing users to download Messenger has paid off. Despite the backlash, Messenger has doubled its user count in 20 months to reach the one billion user mark five years after its debut. Messenger joins Facebook, its acquisition WhatsApp and Google’s YouTube in the billion user mobile user club. The app has racked up some other impressive stats. Each month, 17 billion photos are sent and 1 billion messages pass between people and businesses, 380 million stickers and 22 million GIFs are sent each day and 10 percent of all VoIP calls go through Messenger.
