Edward L. Bernays, the nephew of Sigmund Freud and the founding father of concepts in Public Relations (PR), is known for linking Freudian psychoanalytic theories to influence consumer behaviour.

It is now over 50 years since I read the famous conversation between Max Hart of Hart, Shaffner and Marx and his ad agent, Hart said he would never read long copy. His agent said, "I'll just give you the headline of a full page all-copy ad. You would read every word." "What is it?" asked Hart. "This is the truth about Max Hart," his agent replied. It reminded me of one of my favourite quotes, from Howard Gossage: "People read what interests them, sometimes it's an ad".
