The NBC chimes began as a station identification signal for the NBC radio network, letting listeners know they were tuned to an NBC programme before the network moved into television. The simple three-note pattern became one of the most familiar audio logos in American broadcasting, instantly tied to news, entertainment and the start of a scheduled show. As clips spread online, creators began borrowing it as shorthand for a broadcast itself, using it to frame parodies, announce fake news and signal that something official, or officially silly, is about to begin.
