Piracy is hurting DVD sales, thanks to artificial release delays

Since online piracy started becoming a thing in the late 90's, companies have warned that it cuts into sales. One could argue that piracy can act as a means for generating interest in something, which a person might later purchase. Or that pirates wouldn't be buying the movies/music that they illegally download anyway. A new study does show a link between movie piracy and lost sales, but it might actually be the studios' fault.
