While I agree with klinton that kids these days are certainly more entranced by other mediums of entertainment, it's not without some degree of truth that rudimentary forms have known to capture the mainstream youth. Take reading, for example. Not the major choice, by far. Yet, book series like Harry Potter have gone a long way into turning reading into something a vast number of the youth market craves.
Of course, Potter isn't dumbed down, or written strictly for children, either. The essence, style, and plot of the books continue to evolve, adapt, and mature with its audience. As the readers grow, so does the story, and so does the Potter character.
I feel this could, and maybe even should, be applied to comics as a medium. Evolve, progress, adapt, and mature the books with its readership. Create new titles for new modern markets of youth, and sustain older ones on the maturing audience that grew up with it...
