The heyday of PBS association with Doctor Who — that is the time when the number of stations carrying Doctor Who was not in decline — was roughly from the late 1970s to the mid 1980s. A substantial number of stations continued carrying the programme well into the 1990s, and a two or three still do so as of 2010. Tom Baker is likely the only version of the Doctor who has been screened on every PBS station that carried Doctor Who.
