If you’ve never read it, you should. Dr. Sharp, from the Ehrenberg Institute of Marketing Science, takes aim at many well established marketing beliefs and systematically demonstrates with data that they are often much overblown hype. If you’re a real Marketer, you owe it to yourself to read this book.
I particularly like his concepts of “mental and physical availability” as the most important drivers of brand growth. Advertising’s role is to create greater mental availability, and this is why real world “breakthrough” and memorability are such crucial gatekeeper metrics to advertising success.
I wrote a blog post book review on How Brands Grow some months back, but I recommend you read the book.
