Terrestrial radio looks to high-definition future | ajc.com: "Radio is in the midst of a makeover.

The sound you grew up with -- complete with the occasional pop, hiss or fizz that happens when analog signals can't get through clearly -- is on its way out.

Replacing it is a sound said to be capable of making AM sound like FM and FM sound like a CD. And with it, broadcasters promise, will come a lot more variety.

As radio broadcasters continue battling for listeners with satellite, MP3 players, cellphones and the Internet, they're betting on digital technology to ensure their survival. But despite the companies' investment, many consumers are unaware of the new technology."

I got a little desktop HD radio at Radio Shack on Black Friday last November, and I enjoy listening to the very few HD stations in Atlanta. Here's hoping there's lots more to come.
