From Brave New World Revisited:
In regard to propaganda the early advocates of universal literacy and a free press envisaged only two possibilities: the propaganda might be true, or it might be false. They did not foresee what in fact has happened, above all in our Western capitalist democracies — the development of a vast mass communications industry, concerned in the main neither with the true nor the false, but with the unreal, the more or less totally irrelevant. In a word, they failed to take into account man’s almost infinite appetite for distractions.
Huxley wrote this in 1958 — so I think it’s safe to say even he didn’t fully foresee how very nearly infinite that appetite would turn out to be.
