iBiquity Digital HD Radio technology, backed by 15 of the nation's top radio broadcasters, including ABC, Clear Channel and Viacom, piggybacks a digital signal on a conventional analog broadcast. The major benefits: FM-quality AM, and CD-quality FM. Broadcasters can also attach data, such as artist and song title. Eventually receivers will have onboard memory, enabling them to, say, store real-time weather and traffic that you can access 24/7. The service, of course, will be brought to you by Jiffy Lube, as advertising will offset broadcasters' cost of upgrading. Once you lose the digital signal, analog takes over for a smooth fadeout.
