Dates confusion
Can anyone explain why the gaps between these (magnificent) programmes are not precisely seven years? For instance, the first was made in 1964, the second in 1970, and 28 Up was made in 1985 and 35 Up in 1991. Is it because they are made at different times of the year, or is transmission delayed/brought forward after filming? Any help appreciated, it's been bugging me!
