BBC WAC ref. R9/1: This series of reports runs from July 1940 to June 1953. Its title changed to 'Listener research bulletin' from no. 68 (30/11/1941). The bulletins summarise audience reaction figures, together with a weekly commentary. They were designed to give a summary of the information obtained each week relating to quantitative audience figures (ratings) and qualitative audience reactions, both to networks as a whole and to selected programmes. Some later bulletins are broader in scope, and mention television viewing from 30th December 1951.Between December 1945 and October 1952, they should be read in conjunction with the 'Listener research bulletin supplements' (BBC WAC ref. R9/3). For more on the context of these reports, please see "The good servant: the origins and development of BBC Listener Research 1936-1950" by Siân Nicholas, located in our detailed description section.
