Radio as we used to know it is a thing of the past… Car radios have become an enabler for your FM transmitter so you can listen to your iPod while you drive. With the notable exception of XM, the days of old school over the airwaves radio service is over, while Pandora is paving the road to the future.
Pandora is an internet radio service that allows you to choose a genre or song that you enjoy, and then based on your music choice plays different albums and artists as if you were listening to a radio except you miss out on the disk jockey and talk show hosts.
Pandora makes its profits from commercials that play on a cycle of x # of minutes and then have a premium service you can purchase with various perks to set it apart from the free service.
Another unique aspect to Pandora is that they have reached out to mobile phones such as the iPhone and the Droid by creating Pandora apps that allow users to listen to their favorite stations via their phone.
