DRM works to do the only thing it was ever really meant to do, which is give copyright holders warm fuzzies so that they're more willing to put their content up for sale on legal channels that don't require much in the way of technical savvy to use. Which means that it also works for the vast majority of consumers, since that's all they really ever wanted in the first place. The whole bit about preventing people from copying content is just a feel good story that's told to TV executives in order to further DRM's primary purpose.
