A month prior to the end of the world last year, Madison's Very Own WTDY changed formats and fired the very progressive Sly in the Morning. They were going down hill for many years by that point.
Still, as reprehensible as Sly could be and even though I very, very rarely tuned into his show, I don't celebrate it. I don't celebrate the loss of an outlet of information. But it was a business decision. Even in very liberal Madison they simply couldn't attract and keep the numbers.
Unless one is living in a DUmmie paradise, radio listening is a voluntary act. Nobody forces people to listen to Rush and nobody stopped Madison area liberals from listening to Sly. In the end the market made the judgement and the business people responded.
Even if talk radio is over, and it may be, there is tons of free content all over the Internets.
Maybe some young entrepreneur will figure out how to get rights and start rebroadcasting those for the wifi-impaired?
