Bare with me.
what throws me off
Mostthink the ultimate media is film. People read Harry Potter before anything else as a novel, then movie then comic. Prince Valiant may be another one to consider as it was an early comic strip.
Most don't start in film then become a novel, but maybe a comic. Any novel would probably be a flim then comic, a comic became a novel before film due to cgi restraints.
That's full circle, but I'm not sore if it is all 100% correct. But it's an interesting topic, no one would mind just discussing
