Why DRMSome consumers have decided the problem lies with DRM. However, DRM is merely a tool that serves a purpose. It has a bad reputation because most DRM efforts have gone irresponsibly overboard in destroying user rights under the guise of protecting copyright. In reality, DRM is just a lock. Consumers are aware of why retail stores use locks to prevent theft. There are locks on the doors, physical locks on some merchandise, and sometimes electronic tags that trigger inventory alarms. Everyone knows there are no locks or security systems that are impossible to outwit, but retail locks do work to block the majority of theft related loss retailers would otherwise suffer. The theft they help to stop also prevents retailers from having to cover their losses by raising prices. In the digital world, DRM serves the same purpose. It can be a functional deterrent to mass theft without being an insane barrier to normal use. When abused, DRM fails, just as it did for Sony's MiniDisc and Microsoft's PlaysForSure, and just as its now doing for the Zune. When DRM is created to serve the needs of both producers and consumers, it works to create markets; DRM creates a product that can be sold, creating demand for content that would otherwise be unavailable.
