Techdirt does a nice job describing some of the problems currently facing artists and copyright. Basically, how can you artistically innovate without borrowing?
This is in response to a copyright-related story that recently popped up dealing with the iconic blue, white and red Obama campaign posters. As it turns out, the original image was a photograph taken by an Associated Press freelance photographer. The image was downloaded and altered by someone else to generate the iconic poster image. All this was done without getting the photographer or the A.P.’s permission, and in theory violating their copyright.
