Data collected by Cachelogic, a Cambridge, England-based start-up bears out the ever changing nature of the P2P networks. Their analysis of recent P2P data traffic shows that Bit Torrent, which last year was the most active P2P network has now been supplanted by eDonkey, that has become the network of choice for video file sharing. The study looks at four major networks – Bit Torrent, Gnutella, eDonkey and FastTrack. Video now accounts for 61.44% of file sharing activity on four major P2p networks, while audio is only 11.34%.
