But copyright is not 5 years right now, it's 70 years after the death of the creator. You say the longer the period, the greater the incentive to invest, but there are definitely diminishing returns there. Does anyone actually believe we would have greater investment if it was 80 years? Or 90 years? Maybe it should be 300 years, for all those companies looking for investments that take centuries to be realized. And look at all amazing work that has been produced based on public domain works, the Disney movie empire was basically created on it. I think we can pretty much say that yes, reduced copyright terms would increase the types of movies that we see.
