Munroe was managing editor at the magazine Adbusters in the 1990s, before publishing his debut novel Flyboy Action Figure Comes With Gasmask in 1999. The novel was put out by HarperCollins, a major publishing company owned by Rupert Murdoch, and though the book was successful, Munroe so disliked the experience that he launched No Media Kings as a venue for publishing and promoting his own works independently, and a guide to self-publishing for other prospective writers.
In 2000, Munroe released Angry Young Spaceman through No Media Kings and, in the U.S., Four Walls Eight Windows. He followed up with Everyone in Silico in 2002, which was promoted partly by Munroe's attempt to invoice corporations mentioned in the novel for product placement. An Opening Act of Unspeakable Evil, a novel written in the form of blog entries, followed in 2004. Munroe's most recent books are Therefore Repent! and Sword of My Mouth, graphic novels set in post-Rapture Chicago and Detroit.
Munroe was the founder of Perpetual Motion Roadshow, a North American indie touring circuit that sent 100 writers, performers and musicians on the road between 2003-2007. A former video games columnist for Eye Weekly, he is a founding board member of the Hand Eye Society and has produced projects such as the Torontron.
Jim Munroe, the science fiction author, should not be confused with Jim Munroe, the American magician.
