Imagine harder. Snow White and Cinderella were both compiled in Grimm's Fairy Tales, which was so popular that the brothers produced 7 editions over more than 40 years. It was the Harry Potter of its day. And yet, when Walt Disney was casting about, trying to find a story that would make the first ever full-length animated feature, there was Snow White, published 120 years before, just sitting in the public domain. Absolutely top quality "intellectual property" available for free, and Disney seized the opportunity. I may be painfully naïve, but I can see that happening again.
