I think stuff like this has some effect. It's like advertising. Everybody thinks that what they purchase is rarely, if ever, affected by ads. But when they go to the store, more often than not, they buy the products they have seen the most ads for. McDonalds and Coca-Cola spend over a billion dollars each per year advertising. Asparagus... I don't think I can remember ever seeing an advertisement for a asparagus. Think of this like a pretty big advertising campaign for asparagus.
