" Communism and socialism were portrayed by their detractors as endangering freedoms of speech, movement, press, etc. Such a portrayal was often used as a means to silence voices critical of elite interests . With the Soviet Union's collapse, proponents of the propaganda model have argued that the functionality and credibility of anti-communism has been fundamentally compromised. Proponents state that new, more functional anathemas have arisen to take its place. Chomsky and Herman argue that one possible replacement for anti-communism seems to have emerged in the form of "anti-terrorism". Summary Chomsky and Herman summarize their theory thus: "A propaganda model has a certain initial plausibility on guided free-market assumptions that are not particularly controversial. In essence, the private media are major corporations selling a product (readers and audiences) to other businesses (advertisers). Model The national media typically target and serve elite opinion, groups that, on the one hand provide an optimal "profile" for advertising purposes, and, on the other, play a role in decision-making in the private and public spheres. The national media would be failing to meet their elite audience's needs if they did not present a tolerably realistic portrayal of the world. "
