BBC Books (also formerly known as BBC Publishing) is an imprint majority-owned and managed by Penguin Random House through its Ebury Publishing division. The minority shareholder is BBC Studios, the commercial subsidiary of the British Broadcasting Corporation. The imprint has been active since the 1980s. BBC Books publishes a range of books connected to BBC radio and television programming, including cookery, natural history, lifestyle, and behind the scenes "making-of" books. There are also some non-programme related biographies and autobiographies of various well-known personalities in its list. Amongst BBC Books' best known titles are cookery books by former TV cook Delia Smith, wildlife titles by Sir David Attenborough and gardening titles by Alan Titchmarsh. In the BBC Publishing days, it turned down The Hitchhiker's Guide to the Galaxy, a book which has now sold over 14,000,000 copies worldwide. Doctor Who Since 1996, BBC Books has also produced a range of tie-in novels connected to the television science-fiction series Doctor Who, the only full-length fiction to be printed by the company. Their first release related to the series was a novelisation of the 1996 Doctor Who telemovie published in the spring of 1996. Then, in 1997, BBC Books launched two concurrent series of books, the Eighth Doctor Adventures (EDA) (featuring the then-current incarnation of the Doctor), and the Past Doctor Adventures (PDA), featuring the seven previous incarnations. Between 1997 and 2005 approximately 150 original novels were published for both lines, combined. BBC Books also launched a short-lived line of Doctor Who-related short story collections called Short Trips; Big Finish Productions later obtained the rights to publish the Short Trips books and that series continues as of 2010. In 2005, BBC Books began to phase out the EDA and PDA lines as it launched a new series of books (informally dubbed the New Series Adventures) based upon the newly revived television series. Featuring the Ninth Doctor, the new books were published in hardback (as opposed to the EDA, PDA and Short Trips lines that were exclusively paperback releases). The Eighth Doctor line was discontinued during the summer of 2005, followed by the final Past Doctor Adventure in November. Beginning in 2006, BBC Books continued the New Series Adventures, now featuring the Tenth Doctor, with no word (as of September 2009) whether any more Past Doctor Adventures are planned. The books continue to be published in hardback, with the exception of four novellas, I
