NBC Chimes

NBC Chimes are a distinctive set of three specific tones used by the NBC radio and TV network as an audio signature. Introduced in the 1930s, these chimes help identify the network and create brand recognition. When you hear the three tones—G-E-C—they serve as an auditory cue linking viewers or listeners to NBC. Over time, they’ve become an iconic symbol of the network’s identity, often heard before programs or during transitions, reinforcing NBC’s presence in broadcasting history.
