As a sidenote, before I forget, a friend who likes iTunes let me watch the Motion Comic. It's just shy of "awful," and if my cost estimates are at all accurate, it's a dismal failure. It really is just a step above the old Marvel cartoons, but has the added "bonus" of wooden voice acting.
Anyway...
no one will convince me that today's teenagers will grow into readers of the present 32 page form.
On the other hand, I've lived through the end of music, the end of dance (twice), the end of comedic television, certainly the end of radio, the death of the television networks, and the end of reading. All of them are still alive and kicking, though not necessarily in that order.
The last is probably the most instructive, though. When I was in high school (1990-ish), it was shocking that anybody might read recreationally. Only the "weird" kids read (and why would they, after being force-fed "The Scarlet Letter" and terrible translations of "The Odyssey?"). And, logically, if kids didn't read in high school, they wouldn't grow up to be readers.
That prediction was mostly correct.
However, there's a new generation, and their drug of choice has been Harry Potter. Big, heavy novels that I can't finish because they're so boring. At least, they're boring to me. Kids and younger adults tear it up and obsess about the world, just like comic book fans do theirs. And now they're out of books in the series, so, unsurprisingly, they've moved on to other books. Kids in my neighborhood ask me for reading recommendations, and even I'm bewildered about it.
So, I think comics CAN be something that interests kids. But they have to be about things kids might find interesting and they need to be put in places where kids might find them. It's not hard, it's just that it's a new business line, and that's a hard sell to an existing company that's turning a profit.
