“My headline would simply be ‘DC Comics Triumphant in GN Sales’ rather than using national/area/linguistic categories.”
Mine would be “Other media drive Bookscan bestsellers.” (I’m a whore for subdued alliteration.) What with a blockbuster movie, a not-quite-blockbuster movie that has Angelina Jolie in it, a blockbuster movie trailer (what the hell is that about?), several popular anime, a bestselling series of novels, and a video game that features Disney characters, there aren’t many properties that didn’t get a boost from outside of the field of graphic novels. And two of those have zombies in them.
By the way, does the All-Star Batman and Robin, the Boy Wonder collection include the words “From the creator of Sin City and The 300” anywhere on the cover?
