This Week In Britain was a news series produced by the UK government`s Central Office of Information (COI) in behalf of the Foreign Office and the Commonwealth Relations Office for distribution to overseas TV and cinema networks. Each episode was a 5-minute factual report covering a single topic. It ran from 1959 to 1980 and was black-and white until changing to colour in the early 1970s, sometime around episode 700. The numbering suggests these were issued at weekly or similar intervals. Some episodes appear on various of the British Film Institutes`s (BFI) series of "The COI Collection" DVD sets issued from 2010.
