Messenger is another famous app created by Facebook. Today, this application goes hand in hand with the Facebook app itself for most smartphone users. But, actually, Messenger became available for iOS, Android and Windows devices only in 2011. Before that, there was only the Facebook Chat that was released in 2008. But it was not a standalone application and offered much worse user experience.
According to Statista, as of October 2018, Facebook Messenger was the second most popular messaging app in the world having 1.3 billion monthly active users.
WhatsApp is another messaging application Facebook owns. But unlike Messenger, WhatsApp was not made by the Facebook team — the company acquired it in 2014 for $19 billion. At that moment, the application was already quite ‘mature’, having existed on the market for about five years.
And as we see, that was indeed successful purchase as WhatsApp is the most popular messaging application worldwide nowadays. It has more than 1.5 billion monthly active users and ranked No.1 appby worldwide downloads.
