REPETITION
"Ads seem to work on the very advanced principle that a small pellet or pattern in a noisy, redundant barrage of repetition will gradually assert itself. Ads push the principle of noise all the way to the plateau of persuasion. They are quite in accord with the procedures of brain-washing. This depth principle of onslaught on the unconscious may be the reason why."
Marshall McLuhan, Understanding Media: The extensions of man, 1964, New York: New American Library, Inc., p. 202.
"The power of ads rests more in the repetition of obvious exhortations than in the subtle transmission of values."
Michael Schudson, Advertising, The Uneasy Persuasion: Its Dubious Impact on American Society, 1984, New York: Basic Books, p. 5.
"The incessant witless repetition of advertisers' moron-fodder has become so much a part of life that if we are not careful, we forget to be insulted by it."
The London Times (1886), quoted in Robert I. Fitzhenry, The Fitzhenry & Whiteside Book of Quotations, 1993, Canada: Fitzhenry & Whiteside Limited, p. 17.
