maybe Bauer could do this with Ken's show on GHR in the future?

There is a difference between a single sponsor ‘buying out’ all the advertising for a single Digital feed of a station, than one that has dozens of local opt outs with hundreds of advertisers on FM across the country. Basically the advertising space is Bauer’s main product, the other being their subscription service which wouldn’t serve any purpose with your idea. 

Yes, they could increase audiences massively by ditching advertising, but there is no point to having the highest listening figures if you can’t make money from them.
