I've never understood Americans' obsession with superhero comics. When I was a kid I was reading Asterix[1], Gaston Lagaffe[2], Spirou et Fantasio[3], Lucky Luke[4], Prince Valiant[5], The Phantom[6] and similar stuff. Of course, I've read Superman, Batman and Spiderman also but at least I've had a choice. I can't understand why they don't exist in US, why are the only comic books Americans know superhero comics?

It is a culture thing. Growing up in latinamerica in the 80's and 90's meant that I have access to four of the comics you mention and the ones coming from USA. Asterix's stories for instance were cool but I still preferred reading Superman, and I guess that's because in my original country we were closer to USA's culture than French culture.
