I sit on the Economic Development, Science and Innovation Committee—a very good committee—where we regularly discuss broadcasting issues, and one of the things I find most useful in those discussions is looking at some of the broadcasting data, and particularly viewership figures. They allow us to track interest in programming, and particularly trends up and down, and, more than anything actually, to make assessments about value for money. But one of the challenges we have in doing those assessments is often we get data that doesn't quite line up, or comes from different sources, and so it makes those assessments about cost-effectiveness far more difficult.
