And I think the BBC is far more competitive now than it was in the 80s. I don't know the politics, but apparently when Tom Baker was the Doctor, the BBC was constrained by law as to how much of a raise they could give people each year, and it was less than the increase of the cost of living. So the longer you stayed with a show (both cast and crew), the less you made in relative terms. And clearly they weren't spending the money they saved on people on FX. My vague recollection was that it was the government bleeding the Beeb dry, intentionally. Fortunately, things have changed (new government? New competition?), but by all accounts, the 70s and 80s were a very grim time to be making BBC shows.
