Edwin H. Land Quote

I believe it is pretty well established now that neither the intuition of the sales manager nor even the first reaction of the public is a reliable measure of the value of a product to the consumer. Very often the best way to find out whether something is worth making is to make it, distribute it, and then to see, after the product has been around a few years, whether it was worth the trouble.
