Doctor Who. The books were based on characters who had appeared in the television series as the Doctor's companions, and explored their lives after leaving the Doctor's company. The first two books were Turlough and the Earthlink Dilemma by Tony Attwood, based upon the character played by Mark Strickson in the early 1980s, and Harry Sullivan's War, written by Ian Marter, who had played Harry Sullivan in the series a decade earlier. These books sold well, but after a third attempt (a novelisation of the 1981 Doctor Who spin-off, K-9 and Company) the series ended due to rights disputes between the publishers and the BBC. Other novels would have featured Tegan, the Brigadier, Victoria and Mike Yates. The Sarah Jane Adventures Beginning in 2007, Penguin Books under its Penguin Character Books imprint began publishing novelisations based upon the spinoff series The Sarah Jane Adventures. Direct to video spinoffs Novelisations of spin off productions that were released direct to video. Audio spinoffs Adaptations Generally, Doctor Who stories that have been broadcast will be adapted into print, rather than vice versa. There have been three occasions where print media has been adapted for the screen or formed inspiration for television episodes. The 1995 New Adventures novel Human Nature, written by Paul Cornell and featuring the Seventh Doctor, was adapted by the same author for the 2007 series of Doctor Who as a two part story with the episode titles "Human Nature" and "The Family of Blood", with David Tennant as the Tenth Doctor. Steven Moffat based his 2007 episode "Blink" upon his 2005 short story, "What I Did on My Christmas Holidays by Sally Sparrow", originally published in Doctor Who Annual 2006. Gareth Roberts reused his concept from a 2006 Doctor Who Magazine comic strip story as the basis for an episode of the same name "The Lodger", which was transmitted as part of Series 5 (2010), featuring Matt Smith.
