Mainstream is not a target market. In fact, by trying to blandly appeal to everyone, you wind up not really appealing to anyone in particular.
Yet, in many companies, "niche" is a dirty word, right up there with "polarizing," says Tom Fishburne, in commentary on his cartoon titled "The Target Market."
"The world doesn't need another blandly appealing mainstream idea," says Fishburne.
Rather, the real opportunity is "to find a niche and give them something they will walk over hot coals to buy. Even if it's polarizing. Especially if it's polarizing. By giving something truly remarkable to a niche, the idea can still be appealing to a wide audience. But it needs a niche at the core."
