As of 2011, the company publishes on average 30 to 40 such titles per year, across a range of formats from "making of" books to screenplays to TV companions and novels, and has a backlist reprint program.

Titan Books' first title was a trade paperback collection of Brian Bolland's Judge Dredd stories from 2000 AD.

Subsequently, the publishing company expanded operations, putting out its first original title in 1987 (Pat Mills and Hunt Emerson's You Are Maggie Thatcher).

Its titles include such licensed characters and properties as Batman, Doctor Who, Family Guy, Heroes, Nemi, Superman, Judge Dredd and other 2000 AD characters, the Vertigo comic-book title Sandman, The Simpsons, Star Wars, Tank Girl, The Real Ghostbusters, Teenage Mutant Ninja Turtles, Transformers, The Walking Dead, Life Is Strange, Roy of the Rovers, Dan Dare, WWE Heroes, World of Warcraft and Bloodborne.

In April 2016, Bleeding Cool published a blog/vlog entry pertaining to concerns over Titan's UK reprints of DC titles, specifically cancellations and a lack of updates and communication with readers, as well as addressing the frequent inconsistencies regarding the publication dates of future issues.
