Yeah, on second thought Humanite is probably not the best example, since S&S killed him off (although it was common for villains to "die" back then) and then replaced him with Lex almost imminently and never brought him back.
I don't think the comic medium is dying, but, I don't know if the root of Manga is the way to go, per-say. At least in terms of boosting how many copies they sell.
I think what they are doing with Webtoon is a good start though.
