If they movie industry provided the same service.
If I could go to an official site and download the last episode of a show currently on air in america I would, I'd even watch adverts embeded in the stream. But it wont happen simply because Sky will pay millions for a show, and then it's there problem to make the money back. Its a better deal for the studios if they get their money in one hit from every one in the UK that might want to see it. Of course we are all pay for a mountin of inain crap as well.
Using Usenet ingenerall isn't free, it costs money for a server to get the conent from and it costs money to use newzbin, its not about getting it for free. Its about getting it when I want it. Not having to wait months.
If you think about it, a few years ago we'd have waited 6 months, maybe a year or more for a movie to move from American cinimars to the UK, now often they release at the same time. Now you tell me thats not because of piracy?
Of course if I wanted to see a 3d movie I go to the cinimar, it cost me more or less £50 for me and my partner to go and see Avatar, and I paid it because it was a brilliant movie. I'd even pay it again to see it in the IMAX. If they make good content, then I will pay to see it. If they give me the content when I want it.... guess what? I'll pay to see it.
In the moden world why shouldn't it be on demand. If nothing else newzbin and usenet servers prove that it possible to have thousands of hours of content avalible to download and watch at any time. Maybe the MPA should consider ways to provide the same service as people clearly want it.
