How DRM-based content delivery systems disrupt expectations of "personal use"

We set out to examine whether current, DRM-based online offerings of music and movies accord with consumers' current expectations regarding the personal use of copyrighted works by studying the behavior of six music, and two film online distribution services. We find that, for the most part, the services examined do not accord with expectations of personal use. The DRM-based services studied restrict personal use in a manner inconsistent with the norms and expectations governing the purchase and rental of traditional physical CDs, DVDs, and videocassettes. If adopted by consumers the DRM systems stand to alter the norms governing personal use of copyrighted content and create pitfalls of legal liability for unsuspecting consumers. In conclusion, we present technological and legal considerations which may help current and future DRM system designers better accommodate consumers' expectations of personal use.
