Yes, Copyright Pirates have already killed TV

The effects of piracy are already visible.
Piracy reduces the amount of money available to the programme makers, which inexorably leads to a reduction in quality and choice.
The big problem is that a lot of people do not realise that they are committing piracy when they copy a friend's disk. I support PCs and I've lost count of the number of times I have been asked to copy Microsoft Office onto a computer, for free. Most of these people obtain it from a friend who thinks it's alright to give copies away as long as they don't pay for it.
Producing good programmes for TV, software, or films costs a lot of money. Piracy cuts the producer off from some of their earnings, so they either cannot produce more work, or have a smaller budget for it.
Look at the TV guide, there are only about 6 channels that show any decent programmes and even they intersperse them with cheap rubbish. The schedules are flooded with shopping, betting, phone-in and reality shows. Producers love these because they cost a fraction of the amount that a good programme does.
