The change in time slot did Dr Who no favours, it was always on Saturday evenings along with The Generation Game etc. but then along came Michael Grade as the new controller of BBC1 who hated Dr Who. He moved it to Monday evening at 7:30 where it was up against Coronation Street, a popular soap opera, on ITV, now I was lucky that my mum didn't really watch "Corrie" and so didn't insist on turning over, plus I had a portable tv in my room, but in an era before mass ownership of video recorders, or at least the early days of their popularity, many Doctor Who fans must have missed out. When it came down to a choice between a Mum's soap opera and a Sci-Fi fans programme the soap usually won.
