Facebook Messenger began as Facebook Chat in 2008 and became a standalone app in 2011, with free voice and video calling added in the following years. Its incoming call ringtone became part of daily life for billions of users who kept the app on their phones. As Messenger calls moved into memes and prank videos, creators began lifting the ringtone on its own to fake calls on screen. The sound remains popular because almost every viewer has heard it for real and reacts before thinking.
