Tor was founded by Tom Doherty in 1980 and sold to St. Martin's Press in 1986. Along with St. Martin's Press, Henry Holt and Farrar, Straus and Giroux, it became part of the Holtzbrinck group, now known as Macmillan Publishers.
Tor and Forge are the two primary imprints of Tom Doherty Associates. Forge publishes an array of fictional titles, including historical novels and thrillers. Tor Books also publishes two imprints for young readers: Starscape (for readers 10 years of age and up) and Tor Teen (for readers 13 years of age and up).
A United Kingdom sister imprint, Tor UK, also exists and specializes in science fiction, fantasy, and horror, while also publishing young adult crossover fiction based on computer games franchises. Tor UK maintains an open submission policy and has published authors such as Douglas Adams, Adrian Tchaikovsky, China Miéville, Adam Nevill, Rjurik Davidson and Amanda Hocking.
Tor publishes a range of their works as e-books and, in 2012, Doherty announced that his imprints would sell only DRM-free e-books by July of that year. One year later, Tor stated that it will keep this model, as the removal of DRM was not detrimental to their e-book business.
Tor has won the Locus Magazine poll for best science fiction publisher for 20 consecutive years since 1988 and is described on its website as "the most successful science fiction and fantasy publisher in the world."
In March 2014, the Worlds Without Ends website listed Tor as the second-most awarded and nominated publisher for science fiction, fantasy and horror books, after Gollancz. As of March 27, 2014, Tor has received 316 nominations and 54 wins for 723 novels, written by 197 authors.
