I discovered a free documentary called Steal this film. The film deals with Bit torrent technology. The film talks to such people as the piratebay founders, mininova founders, the electronic frontier foundation. They talk to Howard Rheingold, Siva Vaidhyanathan and Yochai Benkler.
The film looks at how the MPAA tried to bring down Piratebay in 2006 and failed. That trying to stop torrent technology is like one person said 'trying to stop someone pissing out the swimming pool.'
he film looks at the power of the network and history of the network. One thing, the sound is not brilliant and a few years old (2006).
