Craig Baldwin created the great documentary Sonic Outlaws which gives a great overview of the broken nature of copyright law and the struggles that artists face with it. In Spectres of the Spectrum he takes original and archival footage and constructs a science fiction story set in the future. But within the story there is also a healthy (and accurate) dose of the history of the development of technology and the media landscape. While not for everyone, if you are interested in the copyfight it is a fascinating film to watch.
