About this quote
From Scientific Advertising (1923), Hopkins's seminal treatise that argued advertising should be treated as a measurable science rather than a creative art. Hopkins had pioneered mail-order advertising techniques that allowed precise tracking of which copy produced sales, and he insisted that every advertisement be judged by one metric: did it move product?
