According to a new study by Industry Canada, Internet users who download music over peer-to-peer networks buy more CDs than they would otherwise. For years, opponents to the tactics record companies have employed in combating illegal music downloading have argued there is little correlation between the rise of P2P networks and the general sales decline the music industry has experienced over the past decade. Publisher trade groups have strongly rejected any attempt to attack they’re contention that music downloads take money out of copyright holders pockets. Will this latest study cause them to yield any from the litigious and political stance they’ve taken? Unlikely. Michael Geist covers the P2P study fully here.
