Bits were introduced by Twitch in 2016 as a virtual item viewers buy and spend to Cheer in chat, supporting streamers while triggering animated emoticons and alerts. Different Cheer amounts have different sounds and animations, with larger amounts like 500 and above getting more prominent effects. As livestreaming grew on the platform, these alert sounds became instantly recognisable outside Twitch itself. Creators now reuse the 500 plus Bits sound in edits, parodies and soundboards to signal a generous donation, a reward moment or a streamer style reaction.
