Audience Measurement – BARB’s Audience Measurement Service provides estimates of television viewing on a minute-by-minute basis of all channels received in the UK. The sample of 4,485 households is constructed to be representative of the ITV and BBC regions. An Establishment Survey of some 40,000 interviews per year is conducted on a rolling basis to provide the profiles of the television households for panel control purposes and to provide a pool from which new households may be recruited to the panel.
