From a Globe and Mail blog: Among other things, the study found that for every 12 P2P downloaded songs, music purchases increased by 0.44 CDs, or that downloading the equivalent of approximately one CD increases purchasing by about half of a CD. Additionally, the study concludes that half of all songs were downloaded with a "try before you buy" philosophy in mind. The authors of the study stress that in the aggregate, P2P has not been conclusively linked to an increase or decrease in sales, which flies in the face of the claims made by the recording industry. Note to moderators: it was a tough choice of this forum, current events or the politics forum. Having seen other P2P threads, I felt this was the approriate choice, but I apologize in advance if I was wrong.
