Fingeroth wrote Darkhawk, writing all fifty issues of the book between 1991 and 1995. Before that, he had a long stint on Dazzler, wrote the Deadly Foes of Spider-Man and Lethal Foes of Spider-Man mini-series, the Howard The Duck movie adaptation comic and various issues of several Marvel titles, including Avengers, Daredevil, Iron Man and What If?, as well as the Deathtrap: The Vault graphic novel.
Fingeroth resigned from Marvel in 1995 to become editor-in-chief of Virtual Comics for Byron Preiss Multimedia and AOL. From there, Fingeroth served as senior vice president for creative development at Visionary Media, home of Showtime's Whirlgirl, for which he served as story editor.
Currently, Fingeroth publishes Write Now!, a magazine about the craft of writing, for TwoMorrows Publishing. His 2004 Continuum Publishing book Superman on the Couch: What Superheroes Really Tell Us About Ourselves and Our Society has been well-reviewed and is currently in its third printing.
Fingeroth's latest book is The Rough Guide to Graphic Novels, a comic book companion which looks at the medium's history, details sixty "must-read" graphic novels, profiles the movement's legends, and covers film and television adaptations, manga, documentaries, conventions, books, magazines and websites, as well as how to make a graphic novel.
