Vertigo is an imprint of the American comic-book publisher DC Comics. Its books are marketed to a sophisticated audience, and may contain graphic violence, substance abuse, frank (but not explicit) depictions of sexuality, profanity, and controversial subjects. Although many of its releases are in the horror and fantasy genres, it also publishes works dealing with crime, social satire, speculative fiction, and biography. Each issue's cover carries the advisory label "Suggested for mature readers" (regardless of a specific issue's content). As of 2010, Karen Berger is the executive editor of the imprint, and has overseen it since its inception in 1993. Vertigo comics series have won the comics industry's Eisner Award, including the Best Continuing Series of various years (The Sandman, Preacher, 100 Bullets and Fables). Several of its publications have been adapted to film, including Hellblazer, A History of Violence, Stardust, and V for Vendetta.
