Except right now super-heroes as a genre are thriving in live action tv and movies. The MCU, and DCEU, for instance. Superman himself may be taking a break but heroes like Wonder Woman and Aquaman are picking up the slack. On tv DC has had numerous super-hero and adjacent (Constantine, Gotham, Krypton) tv shows. The Arrow-verse is not only expanding its gobbling up tv shows which weren't originally meant to be in their universe like Supergirl, Black Lightning and Constantine, while Marvel's had tv shows on multiple streaming outlets (Hulu, Disney+, Netflix) as well as various tv networks/channels (ABC, Freeform). Marvel and DC are both expanding their branches in tv as we speak. We're in a golden age of live action super-hero media on tv and movies.
Yeah, live action shows. Animated shows? Disney has some Marvel stuff that's not a big deal to most fans. Cartoon Network has Teen Titans Go and has made it clear that they will kill anything else (Brave and the Bold, The Batman, JL Action). Streaming managed to bring back Young Justice which Cartoon Network had killed, and gave us the Harley Quinn cartoon (probably to help with the movie initially, though that didn't work but it's still going so yay!). And there's a HBO Max Aquaman miniseries thanks to the billion dollar movie.
So it's a golden age for superhero shows in live action, but unless something changes cartoon shows seem to be missing the train.
But HBO Max may provide some hope on that front. Problem is Superman probably needs a billion dollar movie to nab a cartoon series there, or see a push in merchandise in general ala Harley Quinn.
