Warner Bros announced it will sell and rent movies and television shows on the Internet using BitTorrent's peer-to-peer technology:
Expected to launch this summer, Warner's service will sell and rent movies and television shows the same day they are released on DVD. Releases will include newer titles such as "Harry Potter and the Goblet of Fire" as well as library titles including "The Matrix." TV shows will include "Babylon 5" and "Dukes of Hazzard." The content will have heavy-duty security features so they can't be pirated.
By using the peer-to-peer service, people will essentially agree to let Warner and BitTorrent turn their own computers into miniservers to help distribute entertainment to other customers around the network. The large files get broken down into small pieces, cutting down on bandwidth costs and time needed to transmit them. A customer receiving a movie could get pieces of it from thousands of other computers before it gets reassembled at the destination computer.
Prices haven't been determined yet. Movies will be cheaper than physical DVDs and TV shows will likely sell for $1. More details can be read over at Wall Street Journal.
