Our PBS station started running Dr. Who, several years back, in the 80's I think. Anyway, I discovered the good Doctor then and got completely hooked. They even had a period when they re-started from the very beginning episode in B&W, and went thru the whole series to the most recent one available at the time. My favorite incarnation of the Dr. is Tom Baker. I think they ran them up until the mid 90's or so.
