Word of mouth is the best medium of all.

Advertising is fundamentally persuasion and persuasion happens to be not a science, but an art.

Advertising doesn't create a product advantage. It can only convey it.

All of us who professionally use the mass media are the shapers of society. We can vulgarise that society. We can brutalise it. Or we can help lift it onto a higher level.

Today's smartest advertising style is tomorrow's corn.

You cannot sell a man who isn't listening; word of mouth is the best medium of all; and dullness won't sell your product, but neither will irrelevant brilliance.

Research can trap you into the past.
