'DRM' stands for 'Digital Rights Management'. It's a way for content owners, particularly in the music industry, to control the way a product is used after it's been sold to the consumer.
Needless to say, for most consumers this really means 'Digital Restrictions Management' and most don't like it. Nevertheless, the music industry has seen fit to shove it down our throats no matter what. Apparently their approach isn't working:
Revenue from digital downloads and mobile content is expected to be flat or, in some cases, decline next year. If the digital market does in fact stall, alternatives to DRM will look much more attractive. (Reuters 1/2/07)
So what's the solution? Things are getting so bad for the music industry that they're actually thinking about dumping DRM and releasing their music as mp3's! Yes, the single most popular digital format on the planet and the recording industry is only thinking of embracing it now -- and then only as a form of market capitulation. Oh brave new world!
