Google Hangouts, launched in 2013 as Google's video and voice calling service, used a bright incoming call tone to alert users when a contact was ringing them. Although Hangouts was later replaced by Google Chat and Meet, the ringtone stayed familiar to a generation who used it for school, work and family calls. Shared widely on soundboards, it is now reused in memes, pranks and short videos because the sound alone instantly tells an audience that a phone call is starting.
