AudioGO Ltd is a primarily digital audio publisher who purchased BBC Audiobooks in July 2010, thereby inheriting all Doctor Who, Torchwood and SJA audio material previously released under the BBC's own audio labels.
They are thus the publishers of the Tom Baker audio range that began with Hornets' Nest, readings of Target Books novelisations, TV soundtracks of missing episodes, some original audio dramas (based upon Doctor Who, Torchwood and The Sarah Jane Adventures), and Doctor Who audio archive material (like the series of Doctor Who at the BBC releases) and documentaries.
In the company reorganisation since the takeover, they have retained the brand identity, "BBC Audio", as an imprint.
History
Previously, the branding BBC Radio Collection was used for release of radio dramas based upon the series: Exploration Earth, 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). The BBC Radio Collection also reissued the audio adaptation of Genesis of the Daleks. Beginning in 2004 the "BBC Radio Collection" branding was dropped, and releases for more recent stories have occurred, even those available on DVD, the most recent to date being an audio version of the 1984 story DW: Warriors of the Deep.
Significant recent releases have included 2008's NSA: Pest Control, which launched a series of original Doctor Who stories that has continued into 2010 and featuring the Tenth and Eleventh Doctors, and AG: Hornets' Nest, a five part 2009 release that saw the return of Tom Baker to the role of the Fourth Doctor.
