238- NBC Chimes

The NBC chimes may be the most famous sound in broadcasting. Originating in the 1920s, the three key sequential notes are familiar to generations of radio listeners and television watchers. Many companies have tried to trademark sounds but only around 100 have ended up being accepted by the United States Patent and Trademark Office -- and NBC's iconic chimes were the first. This episode of Twenty Thousand Hertz features the last person to play the NBC chimes on the NBC radio network, broadcaster Rick Greenhut, as well as radio historian John Schneider. Twenty Thousand Hertz is an audio program that tells "the stories behind the world's most recognizable and interesting sounds."
