In a recent interview, Chomsky expressed ambivalence about the propaganda model that became so successful with Manufacturing Consent. It seems that he disagrees somewhat with the analysis of media content as a function of corporate interests, but is uncomfortable saying so too bluntly because it was largely the work of his friend Ed Herman. Chomsky's real opinion is that economic interests alone can't explain why intellectuals overwhelmingly serve power, since many intellectuals hold safe positions (e.g. in academia) that aren't subject to corporate bosses. I got the impression that Chomsky sees media propaganda as a special case of this more general pattern which he considers more fundamental. Don't have the link handy but can dig it up if anyone cares.
