An out of date business model. If BBC want to be paid they need to keep with the times and switch to a subscription model, like most content providers nowadays.
That's demonstrably false. BBC income is holding up and they're still producing an enormous number of superb unique programmes with it. (Along with a lot of crap, yes, but, I'm a Radio 4 junkie, has a commercial model ever produced a channel of such quality, anywhere? ever?)
