Radio Online

Unlike online TV, which (because of different issues, mostly corporate copyright limitations), do not really manage to become a true Internet international phenomenon; radio stations sometimes manage to do that. In a way, it brings up the question why it doesn't happen with TV: you can hear regular radio stations, with their ads and songs, from anywhere; and in the case of the BBC radio, even clean of ads, but with lots of good music. Why can't it happen with BBC TV?

In any case, the prevalence of radio stations make a tool like the http://www.iheard.com/ radio stations directory very useful.
