An analysis of peer-to-peer traffic has shown that the majority of files being traded are video rather than music.
The survey, by traffic management company CacheLogic, found that over 60 per cent of files being traded were video, with music taking up just over 10 per cent of total files.
The most used video trading system was found to be eDonkey, but BitTorrent is also proving popular, particularly in the Far East.
"BitTorrent is more widely used by 'expert' users, as shown by the high level of less common file extensions," said the report.
"BitTorrent is also increasingly being used for the distribution of legitimate content like game demos, software and software upgrades."
The survey looked at a 48-hour period in mid-July and analysed four popular P2P systems: eDonkey, BitTorrent, Gnutella and the FastTrack family of software, including Kazaa.
Six sensors were set up worldwide with tier-one ISPs in North and South America, Europe and Asia.
BitTorrent and eDonkey are predominately being used for video files, with BitTorrent handling large files and Gnutella having more short video clips.
Files using Microsoft's video formats accounted for more than three quarters of traded files across all networks, with MPEG taking up 15 per cent.
Gnutella is the network that carries the most music, at 69 per cent of its total content, but FastTrack is also popular with music sharers, although 40 per cent of its content is video.
