Facebook’s WhatsApp messaging service now has 2 billion users worldwide, the company announced in a blog post today, up from 1.5 billion and 1 billion users in 2018 and 2016, respectively. That compares to 2.5 billion users for Facebook itself, according to The Wall Street Journal, and 1 billion Instagram users (although that number is from June 2018). Will be interesting to see the future integration of WhatsApp, Messenger and Instagram Direct.
