We've written plenty of times about the importance of the public domain around here, and one of the biggest beneficiaries of the public domain has been Disney, a company which has regularly mined the public domain for the stories it then recreates and copyrights. Of course, somewhat depressingly, Disney also has been one of the most extreme players in keeping anything new out of the public domain, as pointed out by Tom Bell's excellent "mickey mouse curve" showing how Disney has sought to push out the term of copyrights every time Mickey Mouse gets near the public domain. All this despite the fact that Mickey Mouse was almost certainly was an infringing work when it was created, copying multiple sources that were still covered by copyright.
