The 169th episode of Doctor Who airs on the BBC. This is the second Doctor’s second and final encounter with the Daleks, though it is the last Dalek story (and, barring a brief glimpse on a viewscreen in 1969’s The War Games, the last Dalek appearance) for the remainder of the 1960s. Dalek creator Terry Nation withdraws the BBC’s rights to use the Daleks in Doctor Who, intending to launch the Doctor’s enemies in their own series, possibly in America. The prospective Doctor-less Dalek series never comes to pass, and the Cybermen reign as the second Doctor’s most enduring recurring enemies as a result. The Daleks do not headline a Doctor Who story again for five years. This concludes the fourth season of Doctor Who, the show’s first post-regeneration season, and marks the end of producer Innes Lloyd’s tenure as showrunner. This episode is now missing from the BBC’s archives.
Though every episode of the series to date has been flagged for indefinite retention due to its popularity in foreign markets, for the first time, the BBC archive issues instructions to erase most of the first three seasons of Doctor Who. This covers every episode from An Unearthly Child through the final episode of The Gunfighters, and it is at this point that many complete stories are lost forever in video form (such as Marco Polo and The Massacre), and huge swaths of the series’ run are erased as well (much of the 12-part epic The Daleks’ Master Plan). The series thus far has been produced in 405 line PAL videotape, and a new 625 line standard will become the default recording/transmission option in 1968. Many of the erased episodes are recovered years later from the foreign markets to which they were sold, from Africa to the Middle East, but many are never seen again.
