Impossible Astronaut scores AI of 88

Doctor Who: The Impossible Astronaut, scored an Appreciation Index figure of 88, one of the highest figures of the weekend.

The Appreciation Index, or AI figures is a measure of how much the audience enjoyed the programme. It is a score out of 100 based on responses from a 5,000 strong panel.

The score is the joint highest ever received for a series opener, Smith and Jones also scored 88. Last year only two episodes managed a score of 88 or above. Only Lewis on ITV1 scored higher over the weekend, with the show preceding Doctor Who, Don't Scare the Hare receiving one of the lowest scores on record, 46.

In a measure of how successful Doctor Who was over the weekend, no programme on Sunday managed to get more than 6 million watching, including Coronation Street which had 5.9 million viewers; this means Doctor Who remains in 13th position for the week, one which will rise when final figures are released.

David Tennant's performance in United had an audience of 3.2 million on BBC Two/BBC HD.
