Facebook Messenger is more popular than ever, and for some familiar with the social network, that notion might be a bit of a surprise.
Not bad, considering "users did not download it en masse until Facebook stopped allowing them to respond to private messages in the main Facebook app."
Facebook made that change last year: If you want your Facebook chats on mobile, you have to be running this app. So some of its popularity might be by necessity.
And Facebook has been building out Messenger's abilities of late. The M voice assistant is coming to messenger soon, and it supports some mobile payments and now video calling. (Video via Newsy, Facebook)
Of course, maybe we shouldn't put too much stock in one app ranking. It only counts U.S. users, after all.
