FYI, it is impossible for any single company to generate demand, they can only create products that meet existing demand. Demand rises organically over time through the combination of all market forces, cultural trends, etc.

Trying to educate a market that they need your product is a losing proposition. Trust me.

I'm not sure what your claim is here: "Say's Law is hokum." or "Marketing is bunk."

Neither? Judging from the downvotes my comment has been misunderstood. My job is marketing, so I know better than to say it's bunk. For those who still don't understand, here's what Eugene Schwartz, one of the greatest marketers of all time says: "What are you doing when you market something? You are not creating demand for a product. If you think that you are creating demand for your product, you’ve doomed yourself to a lifetime of hard work and failure. You can’t create demand for anything because demand is too large for you to create. The demand has to be out there. The demand has to exist before you even walk into the picture...You cannot create demand. You can only channel demand. Demand is there. Demand is enormous. The bigger the demand, the better your ad is. You are getting in a boat and letting the stream carry you. Just don’t think that you can paddle up against the stream."
