Cachelogic studies p2p trends and traffic, the following data were presented at a Creative Commons P2P-TV workshop by David Ferguson.
Country P2P Preferences
What do people share?
So what do people share?
61,4 percent video
11,3 percent audio
27,2 percent is games/software/etc.
Note that in general video files are larger on average, so people don’t download more video’s, it just generates more traffic.
The average filesize of shared files is 1 gigabyte
What about the Traffic?
As you can see, by the end of 2002 (when BitTiorrent was created ;) ) P2P became responsible for more than 50% of all the traffic on the net.
And p2p traffic continued to grow:
In 2004 1 CacheLogic-server registered 3 million IP-addresses in 30 days
In 2006 1 CacheLogic-server registered 3 million IP-addresses in 8 days
This indicated that the users of p2p networks increased almost 400%
