David Ogilvy, founder of Ogilvy and Mather, in his 1963 autobiography:
I have a passion for landscape, and I have never seen one improved by a billboard. Where every prospect pleases, man is at his vilest when he erects a billboard. When I retire from Madison Avenue, I am going to start a secret society of masked vigilantes who will travel around the world on silent motor bikes, chopping down posters at the dark of the moon. How many juries will convict us when we are caught in these acts of beneficent citizenship?
