My understanding is that 100 years or so after a property has been created (please correct any of this if I’m wrong), that property becomes public domain, so that ANYBODY can create a work based off of it. Many fairy tale characters (Peter Pan, for instance) fall under this domain. And, in about 2033, that will be when Superman becomes public domain, with Batman following a few years after.
Please chime in with your thoughts on this. Is this accurate? And if yes, what does it mean for a new generation of independent storytellers?
