NBC, the American television network, has used its three-note chime as a station ident for decades, making it one of the most instantly recognised sounds in broadcasting. The 1999 Studios theme pairs that chime with a short orchestral arrangement used to introduce network programming. Low-tone edits like this one have since circulated on soundboards and in video edits, where creators reuse the ident outside its original context. Its familiarity does much of the work, instantly signalling television, authority or a big announcement, even in a joke.
