Used CDs and DVDs Market

[anarchae]

I haven't bought a new CD in over 15 years and I haven't bought a new DVD at all. I buy all of my CDs and DVDs in the second-hand (shops, flea markets, online) and overstock (shops) markets for roughly 33% of their cost new (averaged across all sales). This is a multi-million dollar market that has obvious consequences/impact on the sales numbers of the recording and movie industries. I have watched the RIA go after online file-sharers claiming their sales are hurt by such activity, but I hear no mention of this major-marketing of second-hand and overstock media that surely must have more of an impact than online mp3 use/abuse?! In the case of the movie industry, the actual piracy that is occurring is having an undeniable impact, but this secondary market in previously-owned DVDs must assuredly be having (at least) an equal impact. What do you think? Do you get your media the same way?
