I'm interested to hear more of your thoughts. What are the downsides of a shorter copyright (e.g. 7 years) vs a slightly longer copyright? I was trying to think of some scenarios, but I can't think of anything about that time range that might fit. For example if copyright was only 3 years, you could imagine big publishers sitting on things until they were out of copyright so that they didn't have to pay royalties. Most music, movies and TV shows are relevant for only a few years. By 7 years out, they are relegated to the rerun slot. The only thing I can think of are things like novels. So the first Harry Potter novel was quite successful, but it took a while until a movie came out. Movie producers may be happy to wait until it came out of copyright. But that argument might be made for 15 years as well. It would be a different way of doing things, but not necessarily worse, I think. Is it reasonable that Disney can buy up the rights to all Marvel comic books for the last X years? Or would we prefer that anyone could make Marvel comic book movies after a short time -- even if that meant that the original authors aren't compensated. Sometimes I think that even 5 years on software copyright is not a bad length. If you've been updating the software for 5 years, who wants to fork your project from 5 years ago? If you haven't, that's still pretty far out on the revenue tail even for something like enterprise software, let alone games, etc.
