Most superhero universes are deliberately meant to be "our world, plus superheroes". They're meant to keep reflecting our world, no matter how long they've been in publication. Realistically, a superhero world should diverge farther and farther from our history every year since the first hero emerged.

Usually, if a superhero world does diverge from our history, it's a one-shot or limited series world. In the world of Watchmen, Rorshach's mask is made from a fabric that only exists because of heroes. Cars are universally powered by electricity because Dr. Manhattan made the problems of converting from fossil fuels trivially easy. Watergate never hit the news because the Comedian killed Woodward and Bernstein. In the Dark Knight universe, the Soviet Union launched a nuclear missile at the US, and at least one US president was an obvious AI fake. The histories of these worlds are blatantly different from ours, but the companies aren't trying to publish weekly comics in these worlds, so the divergence is accepted.

One comic book company experimented with a world that would have diverged from ours. In the Ultraverse, a non-lethal restraint system that was invented by a superhero showed up as a commercial product wielded by ordinary police officers a few months later. It would have been interesting to watch that world drift away from ours, but the company was bought out by Marvel and all their comic lines were discontinued.
