Saward's "Birth of a Renegade". The former explains the origins of the Daleks and the latter reveals the background of Susan, but both contradict the series and many other stories on the subject. There were also stories in newspapers and comics, storybooks and even serials published on confectionery wrappers and trading cards. In 1979, Nation wrote "Daleks: The Secret Invasion", a novella included in Terry Nation's Dalek Special; this was the first original Doctor Who-related fiction to be published by Target Books. During the 1990s, Virgin Publishing launched a series of Doctor Who-based short story anthologies titled Decalog. A total of five volumes were published, and the last two, Decalog 4 and Decalog 5 were published after Virgin had lost the Doctor Who franchise and did not feature the Doctor. Decalog 4 concentrated on the family of Roz Forrester — a companion introduced in the NAs — over a thousand-year time span. Also during the 1990s, Marvel Comics commissioned the writers of the various original novels under Virgin's New and Missing Adventures lines (see below) to write short pieces entitled "Preludes" which were run in Doctor Who Magazine. These short stories (never more than one magazine page in length) usually focused on an event just prior to a particular novel, or on a character prior to his or her encounter with the Doctor. Some non-novel related short stories titled "Brief Encounters" were also written, including one in which the Seventh Doctor met a future incarnation of himself. (The illustration accompanying this story based the future Doctor on actor Nicholas Briggs, who had played the Doctor in unauthorized audio dramas produced by the fan group Audio Visuals. The Briggs Doctor also appeared in the DWM comic strip.) BBC Books, after it took over the licence to publish original Doctor Who fiction, published several Decalog-style anthologies in the late 1990s under variations of the title Short Trips. Big Finish Productions later obtained a license to produce hardback short story anthologies and appropriated the Short Trips title; Big Finish has also published short story collections featuring Bernice Summerfield, a former companion of the Seventh and Eighth Doctors. In the early 2000s, Telos Publishing produced a series of original Doctor Who novellas, published individually in hardcover; the first, Time and Relative by Kim Newman, was released on November 23, 2001. Although the series was reasonably successful (in spite of the odd publication format, which
