Facebook Messenger first launched on August 9th, 2011 with standalone apps available for the Apple App Store and what was then called the Android Market. Today, Android Police noted that the messaging app has passed a milestone that only two non-Google apps had previously reached-5 billion installs on Android. Overall, Facebook Messenger becomes the 14th Android app to have been installed five billion times.
Most of the 14 apps to hit the 5 billion installs club on Android are Google branded apps such as YouTube, the Google Search app, Gmail and Google Maps. The three non-Google developed apps to have reached five billion installs include Facebook, Facebook Messenger and WhatsApp; all three are owned by Facebook.
