Pretty sure that wasn’t the case.
One of the biggest challenges we had in getting sales for the Young Justice comic was that because it was a tie-in for an animated TV show, the powers-that-be at DC insisted that the comic be branded an all-ages title. This was technically an accurate label. Like the show, our comic was meant to be sophisticated and character-driven in a way that made it compelling for older readers while having plenty of action and being free of language and graphic violence or sexual content that would have made it inappropriate for kids. It was literally intended for all ages.
The problem of course is that most people hear “all ages” and assume that means it’s meant for young kids, and most of those people will further assume that the book isn’t for them without ever checking out the actual content for themselves.
Furthermore, “all ages” books get segregated from the rest of the comics DC puts out. This is true in DC’s online solicitations, the listings in the Diamond catalog, and even at most retail locations. Most comic shops didn’t display Young Justice with the other superhero comics, it was over with Archie and Uncle Scrooge. Over and over I’d talk to fans at conventions who were HUGE Young Justice fans and were the kind of comics fans who were at their local shop every Wednesday to pick up the new books when they came out - and it was news to them that there was a tie-in comic for the Young Justice show. They’d never seen that it existed.
What was particularly maddening is that for a while DC had a category of titles featuring Teen Titans and other books featuring younger heroes. They called this category Young Justice, but the Young Justice book wasn’t in that category, it was in the kids section with Looney Toons.
One of the things Greg Weisman and I pitched to DC Comics after Cartoon Network declined to order a third season of the show was to rebrand the comic to make it clear that it was now the CONTINUATION of the show - effectively the much-desired Season 3 - and remove the all-ages brand without actually changing the tone or “rating” of the book’s content. DC wasn’t interested, but that’s still the book Greg and I would love to do if DC were ever to decide to try and cash in on the continuing Young Justice fan base.
