A number of officially licensed audio productions based upon the long-running British science fiction television series Doctor Who have been produced over the years.
The same year, Tom Baker and Elisabeth Sladen reprised their roles in "The Time Machine", an episode of the BBC Schools series Exploration Earth.
Doctor Who audio adventures diversified somewhat in the 1990s, when the BBC began issuing the soundtracks of 1960s-era serials on cassette and compact disc, some with added narration.
Although more were planned, only two were ever completed: The Paradise of Death (1993) and The Ghosts of N-Space (1996), both written by Barry Letts and featuring Jon Pertwee, (in two of his final performances as the Third Doctor), Elisabeth Sladen and Nicholas Courtney.
In 1998, the Doctor Who Appreciation Society produced a collection of audio adventures entitled Cosmic Fugue 2 in aid of charity.
The format of the Unbound series allows well-known actors such as Derek Jacobi and David Warner to play alternative versions of the Doctor.
Bernice Summerfield, the Doctor's companion from the Virgin New Adventures novels, also features in her own series of audio plays; the character is voiced by Lisa Bowerman.
In 2022, BBC Sounds broadcast Doctor Who: Redacted, a 10-episode podcast written by Juno Dawson and starring Charlie Craggs and Jodie Whittaker.
[5][6] A second, six-episode season aired in late 2023 with Dawson once again writing the show and Craggs, Chimimba, and Holly Quin-Ankrah returning.
