In 2002, Seth Godin asked a simple question that turned the business world upside down: What do Starbucks and JetBlue and Apple and Dutch Boy and Hard Candy have that other companies don't? How did they confound critics and achieve spectacular growth, leaving behind formerly tried-and-true brands?
The world is changing ever more rapidly, and the rules of marketing are no different, writes Godin, the field's reigning guru. The old ways-run-of-the-mill TV commercials, ads in the Wall Street Journal and so on-don't work like they used to, because such messages are so plentiful that consumers have tuned them out. This means you have to toss out everything you know and do something "remarkable" (the way a purple cow in a field of Guernseys would be remarkable) to have any effect at all, writes Godin (Permission Marketing; Unleashing the Ideavirus).
