Welcome

The time has come when advertising has – in some hands – reached the status of a science. It is based on fixed principles and is reasonably exact. The causes and effects have been analyzed until they are well understood. The correct methods of procedure have been proven and established. We know what is most effective, and we act on basic law. Advertising, once a gamble, has thus become, under able direction, one of the safest business ventures.

Claude Hopkins, Scientific Advertising, 1923
