"There have been years when we have seen double-digit percentage growth," Eric Garland, cofounder and CEO of BigChampagne, told Ars. "Compared to that, the last 12 months have been rather flat." BigChampagne notes that the average torrent had 817,588 people participating in May 2006, now that figure had jumped to 1,357,318 seeders and leechers, a growth of about 66%.
Music is also very popular on BitTorrent trackers, except the focus is on downloading full ripped albums and not just single tracks like on P2P networks. There is also a noticeable but small demand for HD content ripped from HD DVD and Blu-ray disc's on several popular BitTorrent trackers. BigChampagne has also noticed a rise in darknet activity but said it's difficult to get a holistic view of what's going on with "underground" networks.
