I'm trying to remember which channels some of my earliest viewing was on. I have a feeling Thunderbirds, Lost in Space and Torchy were all ITV in which case we weren't quite as tuned into BBC as I thought although I'm sure you're right about both the quality and the quantity on the Beeb. Jackanory was followed by two 25 minute programmes before the Magic Roundabout or something similar rounded things off! It all makes for a very interesting trip down memory lane. Oh and the adverts did used to be very irritating!
