Somebody was bound to figure this out sooner or later. If Streaming Radio is great, then IP addressable advertising on that radio is even better.
Subscription-based radio (see Sirius/XM and other models) will not survive. The internet-using populus will reach a point of subscription overload, and decide that commercials aren't really that bad when the entertainment is free (see the last 60 years of radio).
Enter Clear Channel's Katz Media Group. They've struck a deal with Pandora to sell ads. Now, if they'll figure out how to let listeners CHOOSE what kinds of ads they want to hear, and localize those ads via IP address, new life will be breathed into radio.
Read the AdAge article, then think of the possibilities that come with addressable, permission-based advertising.
