|Torchwood One audio dramas|
Torchwood One, and its administrator Yvonne Hartman (played by Tracy-Ann Oberman) made its first audio appearance in Torchwood: One Rule in late 2015. Clearly this was well-received, as a separate Torchwood One audio series was launched in early 2017, with a release following every year since.
