Your original comment ignores the fact that with perfect ad targeting, there will be way more niche spending in your budget since small companies can create and market tightly targeted products cheaply. You’ll be happier with this outcome. With totally untargeted advertising, the whole population will get an ad mix that reflects aggregate spending patterns. The niches will disappear. Only through massive upfront investment into a major marketing campaign will consumer spending shift to a new product. Only the blandest, most mainstream, least interesting among us will be happy with this outcome.
