Objective information is critical for the UK’s television and advertising industry. Each year, £7.5 billion is spent by broadcasters and advertisers on the production and distribution of programme and commercial content. BARB provides an independent, joint-industry currency that is trusted to assess the return on this investment. Dealing with audience fragmentation has been a constant aspect of BARB’s work since our formation in 1981. Fragmentation today is driven by the rise of programmes and commercials being delivered online and on-demand. We constantly develop our measurement techniques to meet the needs of the industry with high-quality data. In recent years we have developed techniques to report the use of BVOD services on TV sets, tablets, PCs and smartphones; pre-broadcast and box set viewing on TV sets and dynamically-served advertising. The Viewing Report 2019 brings to life the latest insights from BARB. We hope you enjoy reading it.
