Was the targetted audience for comics ever teenagers? Wasn't a book called Teen Titans as likely to have been created for sidekicks who were no longer boys and girls rather than as a point of identification? And didn't that whole comics company devoted to teens - Archie Comics - only stumble on the formula by accident?
Was the School for Gifted Youngsters an appeal to youngsters who wish they were so gifted, or is just a good place to start the story of superheroes born with their powers? And were the teens of the future: Legion of Superheroes playmates for Superboy? Or did Teenage Mutant Ninja Turtles accurately parody the prevailing trends with teenagers deliberately at the centre of stories?
I have a feeling that if the comics industry is catching the eye of teenagers, it is guys who were teenagers the first time a character called The Angel appeared (only they weren't called teenagers in them days) Today's teenagers have plenty of other distractions, not least video games and other instant media like cheap DVDs and MP3
