There's AM, FM, shortwave, satellite, Wi-Fi -- and now HD.

HD Radio is the broadcasters' answer to XM(XMSR - Cramer's Take - Stockpickr) and Sirius(SIRI - Cramer's Take - Stockpickr) -- digital streams of music and talk that are broadcast on the FM dial -- along with the stereo analog signals we've listened to for years.

(There's HD AM broadcasting too, but since the AM band is mostly for speech, and not music, HD AM doesn't really matter at the moment.)
