If you haven't seen the documentary done about Chomsky and Herman's book, it's definitely worth watching. I've embedded it here.
It was at the time the most successful documentary ever made by a Canadian producer. It was huge overseas. Shown in about 30 countries. Where it was shown in the US it tended to sell out, but it wasn't shown on television here. In fact it was barely reviewed. The NY Times did review it in a sort of positive review you can read here. The thesis seems to be, according to the NY Times review, "that the government is most responsive to the wishes expressed by the minority of citizens who vote." Huh? It's pretty hard to understand how someone could watch this movie and miss the point so badly.
As far as I know Chomsky never watched the film. He apparently was a bit annoyed because though there was an overwhelmingly positive response he found that people looked to him like he was the leader of a movement. I suppose this violates his anarchist sensibilities. But he doesn't blame the creators and thinks they did the best they could. People naturally react this way apparently.
