BitTorrent: The Third Wave of File Sharing

New York Times:

Three years later, Mr. [Bram] Cohen, 28, has emerged as the face of the next wave of Internet file sharing. If Napster started the first generation of file-sharing, and services like Kazaa represented the second, then the system developed by Mr. Cohen, known as BitTorrent, may well be leading the third. Firm numbers are difficult to come by, but it appears that the BitTorrent software has been downloaded more than 10 million times.

And just as earlier forms of file-sharing seem to be waning in popularity under legal pressure from the music industry, new technologies like BitTorrent are making it easier than ever to share and distribute the huge files used for video. One site alone, suprnova.org, routinely offers hundreds of television programs, recent movies and copyrighted software programs. The movie industry, among others, has taken notice.

It is difficult to measure BitTorrent's overall use. But Steven C. Corbato, director of backbone network infrastructure for Internet2, the high-speed network consortium, said he took notice in May. "We started seeing BitTorrent traffic increase right around May 15, 2003, and by October it was above 10 percent of the traffic," he said.
