Project Dovetail

The UK television industry has changed beyond recognition since BARB’s launch in 1981. Since then, BARB has continuously developed its services in response to fragmenting behaviour patterns. There has been a proliferation of platforms, channels and catch-up services, and in recent years more people have started to watch television through the internet.

BARB’s objective continues to be based on our customers’ requirement for a comprehensive and trusted measurement of viewing to programme and commercial content, regardless of delivery platform. To this end, Project Dovetail was established to deliver total reach of programme and commercial audiences across multiple screens.

Our method for achieving this relies on combing two high-quality data sets:

  • BARB’s panel of 5,300 homes delivers representative viewing information that includes programme and campaign reach, demographic viewing profiles and measurement of viewers per screen.
  • BARB collects device-based data for online TV viewing whenever anyone in the UK watches television via a tagged broadcaster video-on-demand (BVOD) service. These data provide a census-level measure of what’s been watched and for how long.

The multiple-screen viewing figures resulting from Project Dovetail will be released in three stages:

  1. Programme average audiences – multiple-screen programme audience figures for all individuals across four screens: TV sets, tablets, PCs and smartphones. The weekly top programmes on four screens can be found in our new dashboard.
  2. Multiple-screen reach and time spent viewing – unduplicated reach and time spent viewing across three screens: TV sets, tablets and PCs. This total three-screen viewing will be reported alongside consolidated seven-day TV set viewing. The publication date for this is TBC.
  3. Multiple-screen advertising campaign performance – the development of tags for commercials is in process; this will be followed by a new methodology review, development and testing, user acceptance testing and stakeholder review. The delivery timetable is TBC.

To find out more about how we produce multiple-screen viewing figures or for the answers to commonly-asked questions about multiple-screen viewing, such as why smartphone viewing is only available in programme average audiences, please visit our multiple-screen viewing FAQs. BARB customers can also access our new training module.

Project Dovetail meet the first of our strategic priorities: to address the rise of online delivery of programmes and commercials with multiple-screen viewing figures. Our second strategic priority is reporting dynamic ad insertion; you can read more about this in BARB Explained. Our third priority is to address the growth in unidentified viewing on TV sets, which includes viewing to SVOD services like Netflix and Amazon Prime Video. You can read more about this in our future development FAQs.
