They were 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. After the takeover, they retained the brand identity "BBC Audio" as an imprint.
