A fascinating article on the copyright lobbying through the 100 or so years.
Just to add my own 2 bits, I remember one time I was stuck trying to fast forward the anti-piracy warning on a DVD and found that I couldn't. Try it some time, it's programmed so that the viewer has to watch the full track that contains the warning or warnings. At that time I remember musing over the fact that the punishment for the crime of copying a movie seemed unreasonably high, like 10 years of jail time. I mean, that's the kind of sentence that should be reserved for really heinous crimes. Is copying a DVD really at par with rape and murder?
