Subscribe notification chimes rose to ubiquity with the growth of creator culture in the 2010s, when channels began rewarding subscriptions with on-screen animations and matching audio cues. Streamers adopted them for live subscriber alerts, and video editors picked them up as a shorthand for calls to action in intros and outros. Clips like this one circulate on soundboards because they are instantly recognisable to anyone who watches online video, and they still work as a light, non-intrusive way to ask viewers to follow along without a spoken pitch.
