It doesn’t really work that way.
STORM didn’t not sell because people were unaware of it. It didn’t sell because not enough people were interested in reading a Storm solo series.
While you might be able to promote a particular plotline at a given moment, just general “promotion” isn’t a panacea. You can’t trick people into buying a series that they’re not interested in.
“You can’t trick people into buying a series that they’re not interested in.”
What the hell do you call everything that Marvel has been doing for the past decade, then?
“Oh, you don’t like Spider-Man since One More Day? Okay, we’ll get rid of the rotating crew of writers from Brand New Day! Oh, you still think it sucks, because Dan Slott is a hack writer? Well, fuck it, even though sales have sunk to Byrne-and-Mackie levels, we know we can spike the buyership by canceling Amazing Spider-Man and replacing Peter Parker with Otto Octavius! And even though we have to bring Peter back to tie into the movie, we’ll sustain your interest by throwing EVERY version of Spider-Man into the same book! And we’ll give titles to characters like Silk, who no one gives a shit about, but we’ll build interest by having her written by ANYONE OTHER THAN SLOTT.”
