There's no sign of it in their website at this writing, but the folks at CacheLogic have recently conducted an updated study of what sort of content is moving on P2P networks. They found the following:
The mix of P2P traffic by volume, across the 4 major P2P networks:
- Audio: 11.34%
- Video: 61.44%
- Other: 27.22%
65% of all audio files by volume of traffic are still traded in the MP3 format, but fully 12.3% are in the open-source OGG file format (almost all exclusively traded on the BitTorrent network, particularly in Asia)
BitTorrent is increasingly being used for the distribution of legitimate content
eDonkey is now the network of choice for video file trading
I'm supposed to be having lunch with the company next week, and will report back.
UPDATE: In the event, I had to cancel the lunch unfortunately due to other commitments, but the data can be viewed here.
