Intellectual property and Free culture

After I reading the chapter one(Creators) of the book free culture. I have a certain degree of understanding of copyright and free culture. We live in a world that celebrates “property.”  And the ideas , copyrights, arts work are also part of property, it calls “intellectual property”. A large, diverse, and modern society cannot flourish without intellectual property. But actually many great art works is precisely infringed the copyright of others. For example like Walter Disney, he took some old stories and retold them in a way that carried them into a new age like Snow White , Fantasia , Pinocchio, Dumbo. He animated the stories ,with both characters and light. But he Re-interpreting the dark part and make it funny. By today's point of view, his practice is a violation of  “intellectual property”. Another example is Doujinshi what is the comic manga in japan, it take a mainstream comic and develop it differently—with a different story line. Or the comic can keep the character in character but change its look slightly. Actually these works are also illegal. But no one will sue them, because there is plenty of value out there that “property” doesn’t capture. Actually the great “creativity” upon the old stories or original art artwork give people a new view and new exciting experience. Appropriate opening for the copyright will make the artists have more space to creat. Relate to today’s new meidia work like remix, collage, some installations, these art styles all have used the existence of copyright and creativity in varying degrees to a new art works.  Like the book said all culture are free to some degree, and the point is how free is the culture, free culture are cultures that leave a great deal open for others to build upon. However that does not mean we don’t need “property”,  re-creativity is not copy and we should find a balance between intellectual and free culture.
