YouTube introduced Super Chat in 2017 as a way for viewers to pay to pin and highlight a message during live streams and Premieres, replacing the earlier Fan Funding feature. The highlighted message stays visible longer depending on the amount paid, so creators and audiences quickly learned to associate its on-screen arrival and alert sound with support and status. As live clips moved to TikTok, Shorts and edited compilations, the sound was reused outside YouTube itself as a simple ding sound effect signalling a donation, a paid shoutout or a fan trying to get noticed.
