I came across two great videos hosted over at ZDNet about DRM and the ‘real’ explanation of what it does.
ZDNet Executive Editor David Berlind suggests that CRAP or Content, Restriction, Annulment, and Protection, is a catchier phrase than DRM - Digital Rights Management. Why does he think this technology is crap? Once you've bought music or other content to play on one device, it won't play on any other device because of the proprietary layer of CRAP.
He also released a follow-up video on the topic which is also interesting. Too bad the general public doesn’t understand this aspect of DRM.
Digital Rights Management-- or what ZDNet Executive Editor David Berlind calls C.R.A.P. (Content Restriction Annulment Protection) -- has enabled companies like Apple to lock music downloaded through their service into their own devices. Berlind describes an effort to create a DRM standard so content can flow seamlessly between multiple devices.
