I'd be curious to see what TWD #'s were before the show hit. I don't think Outcast #'s have jumped yet as far as I know. Only reason I bring those two titles up is because I have to think a show is really all that's gonna change the Invincible monthly #'s. I mean, seriously. The title has quite possibly the most successful modern day comic book writer AND the amazingly talented (I feel under appreciated) artist Ryan Ottley drawing EVERY month. Only a handful of books on the market reflect that rare occurance where either writer or artist commit to said book for so many issues. It's a win-win. Gotta love Image.
Also, don't forget that Invincible sells a LOT of TPB's.
All true, but the statement still stands - it's a cult book. A great book (in my opinion) but it clearly has a cult following.
It sells roughly as many units between trades and floppies as Captain America monthly according to Kirkman.
