Digital rights management(DRM) is a generic term for access control technologies that can be used by hardware manufacturers, publishers, copyright holders and individuals to impose limitations on the usage of digital content and devices. The term is used to describe any technology that inhibits uses of digital content not desired or intended by the content provider. The term does not generally refer to other forms of copy protection which can be circumvented without modifying the file or device, such as serial numbers or keyfiles. It can also refer to restrictions associated with specific instances of digital works or devices. Digital rights management is used by companies such as Sony, Apple Inc., Microsoft, AOL and the BBC. DRM technologies attempt to control use of digital media by preventing access, copying or conversion to other formats by end users. Long before the arrival of digital or even electronic media, copyright holders, content producers, or other financially or artistically interested parties had business and legal objections to copying technologies. Examples include: player piano rolls early in the 20th century, audio tape recording, and video tape recording(e.g., the "Betamax case" in the U.S.). Copying technology thus exemplifies a disruptive technology. The advent of digital media and analog/digital conversion technologies, especially those that are usable on mass-market general-purpose personal computers, has vastly increased the concerns of copyright-dependent individuals and organizations, especially within the music and movie industries, because these individuals and organizations are partly or wholly dependent on the revenue generated from such works. While analog media inevitably loses quality with each copy generation, and in some cases even during normal use, digital media files may be duplicated an unlimited number of times with no degradation in the quality of subsequent copies. The advent of personal computers as household appliances has made it convenient for consumers to convert media(which may or may not be copyrighted) originally in a physical/analog form or a broadcast form into a universal, digital form(this process is called ripping) for location- or timeshifting. This, combined with the Internet and popular file sharing tools, has made unauthorized distribution of copies of copyrighted digital media(so-called digital piracy) much easier. The DRM on Blu-Ray and HD-DVD could be considered of a second generation type. They are more easily updated, then say Apple's FairPlay, and are harder to break. But the encryption has been broken on HD-DVDs using PC software that reads ALL data coming off the DVD. Due to this "hacking" the DVD companies are considering selling no-PC DVDs. The DVD based DRM is also awkward for customers, because they must update their DVD player firmware/software to play the latest HD/Blu Ray DVDs. DRM has absolutely no benefits for consumers. Music pirates break the DRM and then illegally redistribute the music. Legitimate users are blocked from remixing, editing, converting music, or using it for other means the DRM creators haven't foreseen/allowed. Due to this failed system companies like EMI have partially abandoned it's usage. The reason I'm a loyal consumer to the iTunes Music Store is because they're music DRM is easily broken using QTFairUse. I download the songs, break the DRM and then can use the music for whatever I like. If a online music store didn't have easily breakable DRM then I wouldn't shop there. So in short, DRM free music is better, at least for an advanced music user.
