According to a study on ratings of Internet radio, 60 million Americans tune in each week. 84% of those 60 million Americans, listen to online broadcasts of radio stations that are on the AM/FM channels such as Chicago's WGN Radio 720 or 97.9 The Loop. 62% of online listeners tune in to online-only stations, such as Pandora.
I think people want to hear music everywhere they go, which is why so many people are tuning in online. People are in their cars for a short time commuting and then spend a large amount of time inside. With music on MP3 and iPods, I see less and less radios in people's homes, so when someone does want to listen to the radio they turn on their computer. Now, with cites like Pandora, people are getting the music they want to hear when they want to hear it.
