"[Mort] Weisinger took all these things he didn't care for because they weren't his ideas and turned them to his advantage. Instead of resenting another character with a LL initial as a love interest for the character, he created three or four more and did the whole LL curse. He was really very good, as were his writers, of finding ways to 'brand extend' Superman. They expanded on little themes because he knew -- and this is something we don't see comics do anymore because we don't perceive of them as being for kids -- but he knew that one of the things that was really appealing for kids was a certain sense of repetition. He had a wonderful gift, along with his writers, for being able to balance repetition in theme or in ritualistic kinds of things with new invention. If you look at the DC stuff as opposed to the Marvel stuff, which was created with a different audience in mind, you see that ritual. You see that idea of consistency. Flash's costume always came out of ring. There was the whole 'In Brightest Day, In Blackest Night' oath in Green Lantern. There were certain things in Batman, like the Bat Signal. They knew that those things not only created a comfort zone for the reader, they were things the kids looked forward to. 'Let's see how they do it this time!' It was all about finding ways to do variations on those themes and depending on readers' familiarity with them to create ideas that were new and exciting for kids...those ways of doing comics don't really relate to today, and I don't know if anyone wanted to go backwards, that they could do it."
