BBC Audio is the banner under which the BBC releases Doctor Who franchise-related TV soundtracks, readings of Target Books novelisations, original audio dramas (based upon Doctor Who, Torchwood and The Sarah Jane Adventures) as well Doctor Who audio archive material (like the series of Doctor Who at the BBC releases) and documentaries.
Previously, the branding "BBC Radio Collection" was used for release of radio dramas based upon the series: The Time Machine, Slipback, The Paradise of Death and The Ghosts of N-Space. 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 but for which audio tracks survived (i.e. The Macra Terror and The Evil of the Daleks); in recent years similar releases have occurred for stories that do exist and even for some that have been released to DVD. The BBC Radio Collection also reissued the audio adaptation of Genesis of the Daleks.
Significant recent releases have included 2008's BBCR: Pest Control, which launched a series of original Doctor Who stories that has continued into 2010 and featuring the Tenth and Eleventh Doctors, and BBCR: Hornets' Nest, a five part 2009 release that saw the return of Tom Baker to the role of the Fourth Doctor.
