Justice League Unlimited introduced me to a lot of DC characters I never knew existed before because until then I was only familiar with the big names. I was never a fan of Iron Man as a character until Robert Downey Jr played him. Never much cared for Superman, but, again, I enjoyed the movies & cartoons.Nowadays I don't pick up many graphic novels, and I refuse to by single issue comics because they're too dang expensive.

Today you don't have to read comics to know about and love superheroes. There will always be cartoons. There will always be movies.
