Hugh Pickens writes "General counsel for NBC Rick Cotton and Tim Wu, professor at Columbia Law school, continue their debate about copyright issues and technology on Saul Hansell's blog at the New York Times discussing Fair Use of commercial music and video as the raw materials for new creations. Cotton says that content protection on the broadband internet is really not a debate about fair use The fact that users can 'take three or four movies and splice together their favorite action scenes and post them online does not mean that these uses are fair. There needs to be something more — something that truly injects some degree of original contribution from the maker other than just the assembly of unchanged copies of different copyrighted works.' Wu's position is that 'it is time to recognize a simpler principle for fair use: work that adds to the value of the original, as opposed to substituting for the original, is fair use. This simple concept would bring much clarity to the problems of secondary authorship on the web.' This is a continuation of the previous discussion on copy protection."
