It's abundantly clear by now that no DRM system can stop serious pirates. A DRM system that stops serious pirates, and simultaneously gives broad leeway to ordinary users, is even harder to imagine.

I believe that online paid content hasn't worked for general circulation newspapers because consumers weren't ready for it, because the implementation did not deliver enough value, because content was typically the same as in the print version, and because much of the material was being syndicted by the papers to other publishers or was not protected with DRM technologies to exclude use by others.
