Facebook Messenger is a messaging app developed by Facebook. It allows friends on Facebook to directly message each other and have private conversations - much like texting. Facebook Messenger is available on both the desktop version of Facebook and as a separate mobile app.
You use Facebook Messenger to talk directly to people that have liked your page, making it a useful new communication channel.
