> It has been suggested that this was to make it harder for people to notice how old the programme was This is tempting but I don't know how much credence to give it. It's more to do with a style that was taken on and kept. My father still writes the month in a date using a Roman numeral, e.g. 25/XII/21. The date format has been around for many years. There weren't that many BBC programmes made, even over the course of many years. To try and convince viewers that a programme was not "old" was difficult. It might be black and white, and the quality certainly would have looked dated.
