Static noise has been a familiar sound since analogue television, where a channel with no signal produced a constant hiss and a snowy picture. Online, short static clips became a handy editing tool because they are easy to recognise and need no explanation, appearing in memes, pranks, horror edits and school or hobby projects. This particular clip is only a few seconds long, which makes it easy to drop into a timeline without trimming. Its continued use comes from that simplicity: one burst can signal a break, a glitch or a change of mood.
