A new "Doctor Who" series premiered in 2005, introducing the Ninth Doctor and revealing that the "Last Great Time War" had just ended, resulting in the seeming destruction of the Time Lord society. The episode "Dalek", written by Robert Shearman, was broadcast on BBC One on 30 April 2005 and confirmed that the Time War had mainly involved the Daleks fighting the Time Lords, with the Doctor ending the conflict by seemingly destroying both sides, remarking that his own survival was "not by choice." The episode featured a single Dalek who appeared to be the sole survivor of his race from the Time War. Later audio plays by Big Finish Productions expanded on the Time War in different audio drama series such as "Gallifrey: Time War, The Eighth Doctor: Time War, The War Doctor," and "The War Master."
