Lee Cowan , CBS News, Sunday Morning; Public domain, where there is life after copyright
"Jenkins said, "The public domain doesn't represent the death of copyright. It's just the second part of copyright's life cycle."
The concept of putting an expiration date on intellectual property was something the founding fathers actually put in the U.S. Constitution, "...to promote the progress of science and the useful arts." They left it to Congress, however, to decide just how long copyright terms should last...
Duke University's Jennifer Jenkins said, "Copyright gives rights to creators and their descendants that provide incentives to create. But the public domain really is the soil for future creativity."
There are surely more copyright clashes ahead. Characters like Bugs Bunny, Superman and Batman will all find themselves out of copyright protection soon enough.
Even Luke Skywalker will eventually find himself in the public domain, too, sometime around 2073. That sure seems like a galaxy far, far way."
