Here is a nice video I found from my friend at Stonkington Manor. It's a brief (~55minute) history of copyright and how it affects us today. This really gives you a good insight on how things work behind the scenes and also how the big media companies (Disney, WB etc.) screw over the creators and keep this copyright running so that they are able to take a large cut of the royalties.
Take a look and tell me what you think!
Personally, I think we need to eliminate copyright all together (like the speaker mentions) and move to a new format that helps foster new content and new ideas through the Internet.
