NZ used to have this license fee, but abolished it due to it being expensive and difficult to collect. So now it just comes out of tax, which is far more fair. The UK is behind on things like this. I recall they used to have vans driving around with devices that could check if someone who hadn't paid their license fee , was 'stealing' TV content
Not sure if there is much on BBC iplayer that I would watch, that doesn't get broadcast on NZ TV eventually. Some are also on lightbox or TVNZ ondemand, and prime.Although the big benefit of BBC is very few ads apart from self promos. But a Tivo or a PVR solves that if you you recording TVNZ or Prime.
The problem is that if you start subscribing to all these different online ondemand services, you end up paying as much as you would for traditional pay TV, even though there may only be a few programs on each you would watch. It may only be $5 per week, but just add that to all the other subscriptions.
