November 23, 1963 –
The first episode of Doctor Who, The Unearthly Child, premiered on the BBC, on this date.
Of the 253 episodes of Doctor Who that were produced in the 1960s, 97 no longer exist in the BBC Television Archives due to an archive purge between 1967 and 1978, during which BBC Enterprises destroyed the only known copies believing them to be of no future value.
