Google Hangouts launched in 2013 as Google's all-in-one messaging and video calling app, and its cheerful incoming call chime became the default ring for voice calls placed through the service. When Google wound Hangouts down in 2022 and moved users to Google Chat, the sound took on a second life as retro internet shorthand, much like the Discord call chime, signalling a call or message in memes and edits. Creators keep using it because almost everyone who lived through the 2010s recognises the ring instantly.
