For the first time since 1968, DC snagged the top six spots in the top-ten selling titles of the month. Marvel Comics maintained its hold on the dominant market share in comics, according to Diamond Comic’s monthly sales report. But DC closed the gap from 14.84% to just under 2.5% by dominating the top six, best-selling titles of the month. Blackest Night #4 secured the Number One position, with four other Blackest Night themed titles and Batman and Robin shoring up the rest of the top six slots. Dark Horse held its firm bronze finish over both IDW and Image — who traded off fourth- and fifth-positions yet again. And Archie Comics crept into the Top Ten for the second month in a row, no doubt because of the “Archie marries Veronica” storyline that has been garnering a fair share of media buzz. Here’s a look at the numbers:
