Re: excessive copyright duration?
"If the book,program, magazine, DVD, CD etc is out of print for maybe 5 years, then the copyright should revert to the author(s), or if that's inappropriate, then public domain."
Have you ever wondered how some shops seem to have a permanent sale? They sell goods at full price for the legal minimum time in one shop so as to be able to claim 50% discount later in all the other shops. I can just imagine a "Copyrights'R'Us" warehouse in the middle of nowhere with a huge stock consisting of one single copy each of books, films etc "made available" to the public for purchase. If they can find the place.
