... to yesterdays thought.
It's interesting that when every other form of retail has come to the conclusion that they need to sell their products to ever younger audiences to build brands and take advantage of the buying power kids hold in the form of parent sway that every solution comics has attempted to try and fix their declining readership tends to double down on the assumption that they need to regain the attention of past readers or become more "mature".
Maybe, just maybe, they need to get the attention of new readers. By making comics that appeal to them and that their parents won't blanche at at first glance.
Because the problem is not "too much history" or "Silly Costumes". The problem is that you've started writing for your niche and your niche is shrinking as you fail to bring new people into the fold.
