ii) broadcast anniversary
12 September 1964: broadcast of "Prisoners of the Conciergerie", sixth and final episode of the story we now call The Reign of Terror, ending the original first season of Doctor Who. Ian and Barbara encounter Napoleon; Robespierre is overthrown; the Tardis crew escape, musing on destiny and history. A pretty hefty burden for the team, after nine months of solid performance to turn out the weekly show!
