Series 1 of "Doctor Who" also saw the inception of the "Doctor Who" Christmas Special. The concept of a Christmas Special episode derived of an otherwise ongoing series has been commonplace in UK television for decades. However, the classic series of "Doctor Who" only ever featured one episode with any purposeful Christmas-related content: episode 7 of "The Daleks' Masterplan" was broadcast by the BBC on Christmas Day 1965 and featured The First Doctor William Hartnell offering viewers seasons' greetings direct-to-camera. For the first three series of the revived "Doctor Who", the Christmas Special was held over by the ABC to be broadcast a week ahead of the next series, commencing with "The Christmas Invasion" which the ABC used to kick off Series 2 in Australia on Saturday 8 July 2006 – about ten hours before Series 2 finished in the UK.
