Trend in Commercials

So, I don't know if anyone else has observed this, but it seems like there's a trend in commercials to target stupid people, or at least imply that products are intended for stupid people. Perhaps the marketing people have come to the conclusion that it's more profitable to explicitly target dumb people (larger market? easier to sell to?), I don't know; but I have definitely noticed the trend.

Case in point: Disneyland, and it's two-for promotional campaign. If you haven't heard the spots, it's basically an idiot calling up normal businesses which sell expensive items (cars, fine art, etc.) and asking if he can get a 2-for-1 deal like Disneyland has. Now obviously this is retarded, but that's the point of the commercial: the guy who bought the Disneyland tickets is a moron.

The part I don't understand is: why would you make a commercial for your product that implied that customers are morons? Is the market for idiots large enough (and stupid enough) that it's more profitable to say "only morons buy our stuff" rather than the more traditional "smart people buy our stuff"? Disneyland is not the only ones who are doing this; I see it more and more. It's a strange trend, to tell people they are idiots if they buy your product.

Anyway, just wanted to write about it, cause it puzzles me.
