As well as the regular TV ratings, the BBC also has something called the Audience Appreciation Index, which helps them gauge the reaction from viewers to a program. Itâ€™s an imprecise science, and thatâ€™s before you start trying to get solid numbers and methodology out of the BBC.
So when programs get renewed, is it ratings, AI or managers taking courageous decisions?
Originally provided by the Broadcasters Audience Research Board (BARB), each programmeâ€™s AI score is now researched in-house by the BBC. It has become a shadowy, hard-to-find number which carries an almost mythic quantity for fans of programmes with poor ratings. If the audience love it so much, then a Corporation which does not chase ratings should rely on that for commissioning.
This is still a coarse measurement, not just because of the small sample size, but the single AI number cannot be broken down into why the audience appreciated a programme. Did they like it because it was funny? Entertaining? Made them think? This problem has been there for many years â€” witness the Annan Committeeâ€™s comments in 1974 that â€œ[working] on audience appreciation is too broad a sweep.â€
