Baudrillard's 1981 essay argued something stranger than 'media distorts reality': in advanced media societies, the copy no longer refers to any original at all — it becomes hyperreal.
Chomsky's provocation in 1988: you don't need to censor what the press prints if you filter what it ever sees enough to print.
Postman wrote in 1985 that Orwell feared we would be banned from truth; Huxley feared we would drown in irrelevance. He thought Huxley was the better prophet for television.
