The three-note chime became one of American broadcasting's most recognisable audio signatures, closely associated with NBC's radio and television output. Its simple, repeating pattern made it easy to recognise and remember, which helped it stay familiar across generations of listeners and viewers. Online, short clips of the chime circulate as a shorthand for television itself, and creators reuse it to give homemade videos a polished, network-style opening or a knowingly grand introduction.
