Unlike clips tied to a single show or meme, this is a generic crowd reaction that has become a staple of online editing because it works in almost any context. Cheer and applause tracks have long been used in television studios and live recordings to signal approval, and creators now borrow the same cue for short videos, streams and presentations. It remains popular because audiences instantly recognise applause as approval, making it a quick way to tell viewers that something impressive, funny or heartwarming has just happened.
