Doctor Who: The Big Bang - Appreciation Index
Monday, 28 June 2010 - Reported by Marcus

The Appreciation Index or AI is a measure of how much the audience enjoyed the programme. Any score over 85 is considered excellent. Previous series climaxes have all scored high with series 1 and 2 also achieving scores of 89, series 3 scoring 88 and series 4 scoring 91.
The Sunday repeat on BBC Three was watched by 0.68 million viewers with a share of 3.8%. It convincingly won its timeslot amongst the multi-channel stations.
With Sunday's overnight figures now available, Doctor Who is currently 20th for the week. This should rise considerably when the final figure is released next week, with a top ten place achievable.
Doctor Who Confidential recieved an AI of 86.
