How does copyright protection work on TV?

Every day thousands of people tape programmes and films off their television either to watch once later or to keep for longer, at the end of the credits on 99% of these programmes it has the copyright information.

How can these possibly be enforced? If any person who does not live at the address sees a programme this would surely mean it is a ‘public broadcast’ and so therefore the owner of the house is breaking copyright law.

What about kids sat around listening to music on a hi-fi?

I could go on but face it, we are all law breakers!
