While JLA is a pre-existing concept, probably 80% of the worlds population has never heard of them, or knows who they are.
I know very poor people, almost completely disconnected from the world, who are aware of the idea of the JLA. How? Osmosis, apparently.
And for those 2 people you know, there are millions of others who never gave two shits about comic books!
I can honestly say, in the shop I work, of the 30 or so that work there, I am willing to bet that no more than 3 of them (including myself), have ever heard of JLA.
There is a whole generation of kids who grew up between Super Friends (which hasnt been shown here in decades) and the current JLA cartoons, and they no longer watch cartoons. This would have been their only exposure to comic characters.
You seem to think just cause you live in a poorer country, and know a few people who read comics or watch cartoons, that this automatically means everyone in the richer countries should know who these characters are.
Superman and Batman are a given, but what you have to realise is, some people only know those two characters from tv shows and movies, not comics or cartoons. As the tv shows and movies never mentioned the JLA, theres a strong chance that they have never even heard of them!
