Wrong, it's not public domain until AT LEAST 2023. Does anyone even care about being accurate in their posts here? You also need to understand the difference between copyright and trademark. Mickey Mouse is copyrighted by ALSO trademarked, which is forever and prohibits the likeness used as trademarks without authorization.Interesting example considering Mickey is also public domain.
And even when/if it ever is, who do you think will continue to make money on Mickey? You really think if Disney's powerful lawyers can't stop Mickey from entering public domain that some other company will make significant money from it?
Disney will kick this can until the world ends.
As far as their other content, Disney is the absolute king of content. I can't even list it all in a single post. It's insane. Suffice it to say that Disney owns much of the best content in the world.
