Tor Books is the leading science fiction and fantasy publisher in the United States, known for its deep backlist, author loyalty, and willingness to publish ambitious, ideas-driven work. Founded in 1980 and now an imprint of Macmillan Publishers, Tor has been Doctorow's primary fiction publisher throughout his career.
Tor published Doctorow's breakthrough novels beginning with down-and-out-in-the-magic-kingdom in 2003 and continuing through eastern-standard-tribe, someone-comes-to-town, little-brother, makers, for-the-win, pirate-cinema, homeland, walkaway, radicalized, attack-surface, red-team-blues, the-bezzle, picks-and-shovels, and the-lost-cause. The Martin Hench series — beginning with red-team-blues — represents Doctorow's most commercially accessible work, bringing his ideas about enshittification and financial crime to a thriller audience.
A landmark moment in the Doctorow-Tor relationship was the decision to release his novels under creative-commons-licensing, making them freely downloadable as ebooks while selling print editions. This arrangement, negotiated during the early-blogging-and-cc-era-2000-2007, was unusual for a major publisher and became a proof-of-concept for the argument Doctorow makes throughout his nonfiction: that free digital copies drive rather than cannibalize print sales.
little-brother-published-2008 was the event that elevated Doctorow from cult science fiction author to widely read public intellectual, winning the Prometheus Award and introducing a generation of young readers to questions about surveillance, civil liberties, and adversarial-interoperability.
