Largely comics and pop culture as a whole haven't been too dramatically effected by supers existing, largely due to legal and moral scares in the 50s and 60s. Supers occupy a weird space where effectively they fully own their image and creative rights to their image, including costume, meaning unauthorized depictions are largely not legal. On top of this, comics fell into a lot of issues where between laws and the moral panics of the 50s/60s, superheroes are of course not allowed to portray themselves as superheroes from comics(as in someone cannot claim to be the real Captain America, and dress as him), comic companies are not allowed to "back" or fund superheroes in any way. This leads to any comics depicting real superheroes largely being about retired heroes, as if they were about active heroes, it would have to be authorized, but no money would be able to go to the hero. And there has been argument that even this would fall into "backing" a super. Movies suffered from similar fate, although not quite as restricting.
By the 1990s, super hero comics, once a mainstay of the comics industry began to dwindle greatly in popularity, largely from a combination of legal restrictions as well as people generally feeling they were too close to mimicking real events. Historicals, sci-fi, and fantasy comics still generally sell well.
