BARB asks for tenders on Dovetail task 9 July 2013 BARB has this week issued an invitation for research agencies to design a hybrid measurement system. This builds on the recent news that BARB has started the process of collecting census data for television viewing through all computer devices. The invitation to tender is part of Project Dovetail, established by BARB to capitalise on the complementary strengths of representative panel data and census-based site-centric data. The daily data that BARB produces are used to account for over £6bn of investment decisions each year. This gold-standard currency is trusted because of the quality and representativeness of the information. Users can establish who is watching in a way that delivers programme reach, demographic viewing profiles and measurement of viewers per screen. Site-centric data provide highly granular information about demand for individual pieces of content. This allows more detailed measurement of long-tail digital consumption. Justin Sampson, chief executive at BARB, said “new data sources are important to ensure that BARB continues to provide a complete, high-quality picture of television audiences. We’re already on track to deliver greater insight into the viewing that takes place on computer devices as a result of last month’s news. Now we are taking another big step by asking research agencies to pitch for integrating this data with the viewing figures that our users are already familiar with.” Research companies are being asked to submit responses by the end of September 2013. Further news on a timetable for delivery will follow. Read more about BARB’s strategy. The invitation to tender can be made available to potential suppliers.
