BitTorrent, developed in 2001, has gained in popularity as a way to download large files (like movies) by sharing the burden across hardware and bandwidth. Reportedly, more than a third of all Web traffic now comes from BitTorrent clients. BitTorrent and the entertainment heavyweights have since joined forces. The newly released BitTorrent Entertainment Network launched recently with thousands of industry-approved movies, television shows, games, and songs for sale and rental.
