Doctor Who is a British science fiction television programme produced by the BBC since 1963. Hundreds of novelisations of the series have been published by various publishers, the majority based on the original 1963–1989 run of the series. History Frederick Muller Ltd. Frederick Muller Ltd. commissioned David Whitaker to novelise the first Dalek serial under the title Doctor Who in an Exciting Adventure with the Daleks, which was published November 1964 in hardcover just in time for the second Dalek serial, The Dalek Invasion of Earth to be transmitted. The success of this book warranted two reprintings by 1965 and led Frederick Muller to commission two further novelisations, Doctor Who and the Zarbi and Doctor Who and the Crusaders, which were published in 1965 and 1966 respectively. Sales of these books did not live up to the first and so the short range was brought to an end. Doctor Who in an Exciting Adventure with the Daleks was reissued in paperback October 1965 by Armada Books, an imprint of May Fair Books, with new illustrations. Doctor Who and the Crusaders was reissued in paperback in 1967 by Green Dragon, an imprint of Atlantic Books, again with new illustrations. All three books with reissued in hardcover in 1975 by White Lion, all featuring Tom Baker's Fourth Doctor on the cover while retaining the First Doctor illustrations inside. Target Books In 1972 Universal-Tandem Publishing was looking to create a children's book imprint, Target Books. In a visit to Frederick Muller's offices, the three 1960s Doctor Who books were optioned, and then the BBC was contacted with a view to publish new books. This call to the BBC met with enthusiastic support from the current script editor, Terrance Dicks. The Doctor Who novelisations quickly became a backbone of the imprint, surviving corporate acquisitions and novelising almost every Doctor Who television story. New novelisations under the Target imprint came to an end in 1991 (although three more were published under their parent company's new Doctor Who Books imprint). Reprints under the Target imprint continued through 1994. A short series entitled The Companions of Doctor Who comprised the novelisation of K-9 and Company along with the original works Turlough and the Earthlink Dilemma and Harry Sullivan's War. In addition to the television serials, three scripts from the cancelled Season 23—The Nightmare Fair, The Ultimate Evil and Mission to Magnus—were novelised. The former sold less well
