They go online and visit barb.co.uk — you can too. Barb (the Broadcasters Audience Research Board) is owned by the major UK TV channels and the Institute of Practitioners in Advertising. It uses a special panel of 7,000 households in the UK, selected based on geography, demographics and TV platforms, which represent the entire UK population. Viewers in each household have special remote controls with unique buttons for each person, to help record exactly what programmes were being watched and when.
This data is added to data from the household's Wi-Fi router to understand what video subscription or on-demand service was being used, and data from connected devices to track viewings of a broadcaster's video on demand.
