I think that the stuff with which you grew up should enter the public domain around the time you're an adult. Anything you were watching or reading while growing up is a key part of your culture, and I don't think it's reasonable for it to be kept in the hands of a few people. For me the proper range should probably be around 20 to 30 years, but I'd be willing to entertain special restrictions in certain conditions. Beyond that, I think that we don't do enough for the sake of preservation. I think for software to have full copyright protections it should be required to preserve a copy of the source code in the library of congress. And any library or tool licensing from the era should be restricted to the same duration as the copyright.
