I do not know who the genius was that coined the phrase "digitally restricted media," but it is the perfect definition for the acronym "DRM." At present, it is widely known to mean "digital rights management" which is the copy protection being used to restrict playback of downloaded media (music, movies, etc.) to certain software and hardware. I am going to go along with the new meaning I have now heard, the "digitally restricted media." It seems more accurate and in line with the money hungry music and movie industries.
Like I said, I do not know who came up with it, but I first heard it as an email or call-in on the HDTV Podcast, which you can find here.
