Google Hangouts launched in 2013 as Google's unified messaging service for text, voice and video calls across Android, iOS and the web. Its default notification tone became widely recognised during the years when Hangouts was preinstalled on many Android phones and used inside Gmail. After Google wound the service down in 2022 in favour of Google Chat and Google Meet, the chime survived online as a standalone clip. Creators now reuse it for fake message pranks, tech nostalgia and instant alert jokes long after the app itself disappeared.
