There’s an interesting article on arstechnica about why pirate downloads of videos are outpacing legal ones. I particularly liked their term for Digital Rights Management:
Another obvious factor is Content Restriction Annulment and Protection (CRAP) technologies, more commonly known as DRM. Consumers who pay for digital video downloads want to be able to play those videos with the software of their choice, without a lot of trouble or the imposition of additional limitations. Consumers also want to be able to convert legitimately downloaded content to other formats so that it can be played on mobile devices.
The rest of the article is worth reading too.
