"No room for Super-Turtle!"
Neil Gaiman points to this cute cartoon about the origins of Vertigo.
It’s hard to believe that DC’s Vertigo line and massive bookstore presence (which, in turn, opened the way for other graphic novels, arguably including the current U.S. manga boom), plus the successful careers of several writers (including Gaiman), can all be traced back to DC hiring a little known British writer to take over a failing revival of a short-lived 70s horror title.
