Digital Rights Management is quickly becoming pervasive in electronic devices of all sorts. This minimally-technical overview of DRM systems in use now and planned for the future will show you how and why your ability to make use of electronics is being reduced by corporate desires to increase profits and exercise control over their products. The emphasis here will be on DRM systems that have gotten little publicity. The DVD CSS system will be touched upon but most of the time will be spent describing systems for controlling television broadcasts, DRM built into CPUs and BIOS's, and other areas that haven't gotten nearly as much attention as CSS.
