In 1993, during the boom years of the superhero comic book bubble, DC Comics was all about big superhero mega-events like the multi-million selling “Death of Superman” issue and Knightfall, where the villain Bane broke Batman’s back, crippling him forever (read: a year). But the most important event — the one with the most lasting impact — didn’t involve any super-fights or intergalactic cyborgs. That year, DC launched Vertigo Comics, an imprint that became the home for independent comics, creator-owned material and more mature storytelling.

Initially populated by comics that had migrated from the superhero-centric DC Comics, the content soon began to focus on darker, more sophisticated stories that were largely free of capes and tights, including iconic works like Sandman, V for Vendetta, Y: The Last Man, Transmetropolitan and Preacher.

As Vertigo turns 20 years old, the imprint will also see the departure of Karen Berger this month, the executive editor and founder who shaped and guided Vertigo since its inception. It’s a historic change that marks a major shift for one of the most influential imprints in the history of comics, particularly as the barrier between the DC Comics and Vertigo has become far more semi-permeable, thanks to crossover appearance by Vertigo characters like Sandman‘s Death and Hellblazer‘s John Constantine swapping permanently in the DC Universe proper.

With two decades of impressive work behind Vertigo Comics — and the end of an era at hand — Wired takes a look back with an interactive infographic by Digital Design Director Tim Leong that compiles every ongoing series the imprint has every ongoing series published under the Vertigo Comics banner. (Issues of series published by the DC Comics or Helix lines are not counted.)
