Airing where ? Mars maybe or cable. I've never had anything but normal broadcast TV, no cable or dish.
On the BBC. First airing on 23 Nov 1963 (which makes the show older than I am). Serialized half hour episodes of a two to three hour adventure. I picked up on it after catching the the last episode of "Genesis of the Daleks" in 1982 on a Chicago PBS station. Its mostly run on PBS stations here in the U.S. with the occasional side movie stints on cable channels.
Most people overlook it since prior to 1986 or so, the props were cardboard, the costumes aliens cheap rubber & grease paint and the effects were on par early Outer Limits. Great fare for adolescent males though, since the Doctor usually had fetching female companions such as this...

Oh, and the occasional man or droid, but who cares about them?
