Titan Publishing Group — parent company to both Titan Books and Titan Comics — is a book and magazine publishing company which has enjoyed several different BBC Worldwide licenses to publish various DWU tie-in works.
In the 1990s, they published a number of Doctor Who scripts in the Doctor Who: The Scripts series, and thus gave fans their first glimpse at "official" versions of the scripts of some of the show's more popular serials, including the first publication of the unproduced script for The Masters of Luxor. These books were produced for the UK market but also received limited distribution in North America.
From 2008 to 2010, Titan published Torchwood The Official Magazine, featuring behind-the-scenes articles and original comic strips and short stories based on the spinoff. Publications spun-off from the magazine included a graphic novel compiling the story arc COMIC: Rift War and the hardcover publication Torchwood The Official Magazine Yearbook in 2008. As with the script books, the magazine and spin-off publications were primarily produced for the UK market but were imported to North America by speciality retailers.
From the summer of 2010 to early 2011, Titan's American branch published Torchwood: The Official Comic, which ran for six issues and reprinted most of the magazine's comic strips and short stories for North American audiences. The first issue was cover-dated September 2010, but distributed in the summer. This comic was distributed in North America but not in the UK.
In issue #24 of Torchwood Magazine, Titan announced that due to BBC Worldwide realigning its promotions for Torchwood related to the 2011 broadcast of TV: Miracle Day, it was discontinuing publication of the magazine effective with issue #25. The US Torchwood comic was also cancelled before it was able to reprint all of the magazine's comic strips and short stories.
Titan once again began publishing Torchwood material with the advent of Torchwood (2016), a wholly original comic book.
Titan returned to the Doctor Who franchise when it was announced in late 2013 that its American subsidiary had picked up the North American licence to publish original comics based upon Doctor Who after the expiry of IDW Publishing's contract with BBC Worldwide.
All three series have been published concurrently in North American comic book shops, with digital editions available for purchase in Europe and the United States. In the United Kingdom, Doctor Who Comic, which had all three of these ongoing series inside, launched in February2015. It was companioned by Doctor Who: Tales from the TARDIS, which reprinted miniseries stories, but eventually grew to print main series stories, succeeding Doctor Who Comic.
