Technology - BitTorrent: The Great Disrupter - FORTUNE

"What he came up with was BitTorrent, a deceptively simple program that has grown into the hottest way to download anything bigger than a music file from the legal (like militaryvideos.net's amateur videos of the war in Iraq) to the infringing. It makes pirating a copy of the latest movie out of Hollywood a snap. All it takes is a free download of the BitTorrent software something 45 million people have done and anywhere from a few minutes to a few days."
