[[Patrick Troughton]]'s Doctor was an impish figure, whose gimmicks included playing the recorder. In this period, much of which is lost, the program felt the influence of [[Star Trek]] somewhat.

===Third Doctor (1970-1974)===

The third Doctor was Earth-bound for much of his tenure, a move that was partly motivated by budgeting constraints in production. In the stories themselves, this was explained by the Doctor's race - the Time Lords - imposing an exile upon him due to alleged crimes prosecuted in ''The War Games''. During this time, the United Nations Intelligence Taskforce ("UNIT") was a key element of plots - the Doctor was officially UNIT's scientific advisor, but he frequently attempts to break free of the Time Lords' imposition of exile.
