BARB – Broadcasters’ Audience Research Board: This organisation compiles audience measurement and TV ratings in the UK. It is jointly owned by the BBC, ITV, Channel 4, Channel 5, Sky and the Institute of Practitioners in advertising. Data is collected by participating viewers, who have a box on top of their TV set which tracks the programmes they watch. There are 5,100 homes in the UK with one of these boxes, tracking the viewing habits of 12,000 individuals. This means that each viewer with a BARB reporting box represents over 5.000 people. Participants use a handset to indicate who is watching any time they have shows on. Data is collected overnight and published the following morning for use by TV stations and the advertising industry.
