I know that my Mom told me that Google owns YouTube a few years ago,  but what I want to know is why the Warner Bros./Don Bluth movie 'Thumbelina' is now owned by 20th Century Fox.

I remember that when I was almost 21, I did buy 'Thumbelina' but then noticed the 20th Century Fox symbol on it and that got me a little shocked and a little annoyed. (I did like the cover of it, though.)
