That's because events such as these (and subsequently the comics code authority) made it legally and financially nonviable to do anything but spandex comics for kids. Before that, the contents of comics was as varied as the films and pulp fiction of the time. Imagine if during the time of the Hays Code people were burning celluloid in the streets (look up public comic book burnings) and as a reaction studios made nothing but Laurel and Hardy and Ma and Pa Kettle films and it wasn't until the 80s that any kind of adult film-making re-emerged in the mainstream in any substantial way.
