Did you ever notice on the CBS TV show THE BIG BANG THEORY though they reference both Marvel and DC Characters( even had Stan Lee make an appearance in an episode) they never present Marvel Comic books, graphic fictions or posters. Even in the comic book store all you see is some independents( like Hellboy) or DC comics. However they will show Marvel toys such as the “Hulk Hands” episode and so on.
I have wondered why they do not show any Marvel Comic volumes on the show.
The thing that I think confuses most people is that CBS has no real connection either way to DC or Marvel Comics, so it seems weird that they would have a preference either way. However, the hook is that CBS does not own the prove, Big Bang Theory- CBS simply airs it( and make advertising revenue off of it ). The show itself is owned by Warner Brothers, who also own DC Comics, which is why you largely assure DC Comics products on the show and hardly ever Marvel Comics( although occasionally you’ll see them use Marvel merchandise like Hulk hands ).
