Obviously he was talking about the U.S. pamphlet-sized comic (1930 to present) in general and the superhero/adventure genre of comic book (1938-present) in particular.
If you has followed the link to the
The History of Comic Books that I provided you would know the U.S. pamphlet-sized comic (17" wide x 11 tall") goes all the way back to 1902 and the first Superhero book (a reprinting of the Phantom strip) was in 1936 and the adventure genre was well represented by the likes of Flash Gordon, Popeye, Dick Tracy, Terry & the Pirates, and Mandrake the Magician.
Having just presented an academic paper dealing partly with the 18th-Century origins of the graphic novel, I appreciate your repeated linking to the Platinum history web-site. Now maybe I'll learn something!
(I urge everyone interested in comics history to check out the essay on Platinum/Victorian Age Comics by Robert Beerbohm et al in the Overstreet Price Guide. Beerbohm also maintains a great discussion group on Yahoo about pre-1940 comics.)
But I stand by my original statement: regardless of
actual comics history, it seems apparent from the context of his remarks that Defender was referring to what most people think of as the American comic book/superhero (1930s-present). Any other reading is just pointless nitpicking and flame-fanning. Accidents, one-offs, and contested definitions of superhero (vs costumed adventurer, etc) notwithstanding. After all, what's a few years between friends?
And for the record, a good case can be made that the first modern-size comic book was actually the first US comic ever, the Brother Jonathan printing of Rudolph Topffer's Obadiah Oldbuck, circa 1840.
