Nonsense. Put the BBC behind a paywall without adverts and charge the same amount as the current licence fee. If the BBC is as good as people here claim then the service will continue as is.
How do you do that?
Come up with a method of moving a current free to air broadcaster entirely behind a paywall without requiring end users to have to modify or purchase new equipment or rendering existing equipment useless.
I'm just off out in the car - how would I access Radio 2 behind your paywall?
