The big money interests are digging their own grave as far as I'm concerned. They build these big life + 95 year fences around their factory work and forget that fences work both ways; not only have they kept their factory work safe from the public, but they have given the public every incentive to do their own work and ignore the factory work. Sooner or later, as Britney has shown, factory work will be so blandized and homogenized that it will only be used for elevators and dentists' offices. All the real popular culture has long since moved beyond their fences and out of their control. I don't know how much is under Creative Commons licenses, but I suspect it will only increase, and the entertainment factories have locked themselves out of that with their copyright fences.
