"A few years ago, the Bose Acoustics Corporation had a new product, the Bose Wave Music System. And their ad campaign for it was not successful until they changed one thing. At the top of the ad they said, "Hear what you've been missing." And that caused the skyrocketing of the interest in purchasing of the product. Why? Because with something new, people are uncertain, and when they are uncertain, they want to avoid losses."
