Pandora radio is probably one of the most innovative personal radio stations today. Why you ask? Well because it’s only what YOU want to listen to. www.pandora.com is a giant network of a very large collection and database of music. You type in the band you want to listen to and then it cycles through and plays only bands that play similar music. And it’s surprisingly (almost in a scary way) very effective!
If you’re into ska and you type “Reel Big Fish” as the band to play, it will also play other bands like LEss Than Jake, Goldfinger and Suburban Legends. All very similar style bands. I personally have no idea how it works but i like to think it’s magic performed by a higher being 
.
How do they make money? Well after about every 8 songs, a mandatory commercial will be played for about 15-30 seconds. As well as the multiple ads displayed around the site to produce revenue. An upgraded version is even available for purchase which allows unlimited play time. Pandora even has a user friendly Application for the iphone and other smart phone likes the droid eris.
So how will radio survive if people can listen at any time to whatever style they want? Pandora lacks the conversational style we find in radio which keeps us company on our morning commutes and long drives. But really, mostly time will tell.
