BBC Physical Audio previously known as BBC Audio, which was later accuired by AudioGO, are the producers of official BBC audiobooks. Previously, the branding BBC Radio Collection was used for release of radio dramas based upon the series. Also released under the banner — although technically incorrectly as they were never intended for radio — were edited TV soundtracks taken initially from episodes that had been deleted by the BBC.
AudioGO entered administration after significant cashflow issues were discovered in October 2013. Rights to AudioGO's BBC-licenced content (including Doctor Who) for the UK and the rest of the world excluding North America, Australia and New Zealand, were transferred to Random House in December 2013. Since November 2014, BBC Physical Audio have released Doctor Who audiobooks.
