BBC America to air vintage Doctor Who serials

In celebration of the Time Lord's 50th anniversary, BBC America is reminding fans that "Doctor Who" existed for many years before his most-recent revival.

The network is celebrating the Doctor's past by airing a classic Doctor Who storyline each month as part of series titled "The Doctor's Revisited." It launches this Sunday with a broadcast of the 1964 adventure "The Aztecs," starring first Doctor William Hartnell.
