I am being taken out of context, I am not talking about making money I am talking about copy right protection. Disney has a vested interest, whether making money or not on a work, that Joe Schmo does not start reproducing a given work 1 to 1 and selling it as their own.
You may be right most income is derived from a work in its first 60 years, or that media created 60 years ago was not expected to be marketable 60 years later. Though I do not know this to be a historical fact, 60 years ago (1953) there was plenty of evidence to suggest a given work by a US author has plenty of commercial appeal after a mere 60 years of existence (Walden Pond, Civil Disobedience, Uncle Tom's Cabin, almost any Mark Twain novel).
