What has changed in how BARB reports television viewing? People are increasingly watching television programmes on devices other than the TV set, be it on PCs, tablets or smartphones; the UK television and advertising industry needs a trusted, independent source of these multiple-screen viewing figures. BARB established Project Dovetail to meet this need. Since 2015, we have been supplying these figures at a device level. Now we are introducing people-based measurement of viewing on devices. For more information on Project Dovetail, including our method for producing multiple-screen viewing figures, please visit the Project Dovetail overview page. How are multiple-screen viewing figures being released? How do I access them? Multiple-screen viewing figures are being released in three stages: DataAvailability on BARB website Availability for BARB customersPublication date 1Programme average audiences - For all individuals across four screens: TV sets, tablets, PCs and smartphones - Published 8 days after transmission Weekly top 15 programmes by broadcaster group/channel on four screens via new dashboard in viewing data section Customer log-in to access weekly top 50 programmes by broadcaster group/channel on four screens via dashboard.

Delivery timetable to be finalised.Date TBC How does BARB produce multiple-screen viewing figures? Multiple-screen viewing figures are being released in three stages: BARB has two sources of data. 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. Viewing data generated from this census-level dataset are based on device usage and do not represent the number of people that are watching. We collect observational data continuously from our nationally-representative panel of 5,300 UK homes. Over 60% of these homes have had software meters installed that track our panel members’ viewing on tablets and PCs. We know how individuals view across different screens because we measure viewing on all devices in the same panel. To generate multiple-screen viewing figures, we need to understand two aspects of online TV viewing from the panel: The extent to which people watch BVOD services on their own, or as part of a group; this is known as viewers-per-view. What type of people watch BVOD services on different devices. Simply put, we are then able to turn device-based data into people-based viewing figures by aligning programme audience levels to the census data, while aligning programme audience profiles to the panel data. This results in multiple-screen viewing figures. Read this BARB Explained to find out more. Which BVOD services are included in the four-screen viewing dashboard? The four-screen viewing dashboard includes multiple-screen viewing figures for tagged BVOD services only. At present, these are: All4, BBC iPlayer, ITV Hub, My5, S4C Clic, Sky Go, STV Player and UKTV Play. What are the known issues with the multiple-screen viewing data in the four-screen viewing dashboard? The following known issues affect the four-screen viewing data in the dashboard: Online data are not available from the following BVOD services: STV web live, S4C-Clic Android on-demand / live. This reduces the tablet /smartphone viewing reported via the S4C Clic service. On-demand viewing data on PCs, tablets and smartphones are currently not available for the following broadcasters: A+E Networks UK, Fox International Channels UK and Viacom. Live viewing data on these devices for all these broadcasters, with the exception of Viacom, are included. PC, tablet and smartphone viewing figures may all appear as zero for a programme where the online viewing has not been linked to the linear broadcast. NB. Where broadcasters have not supplied a broadcaster content ID (BCID) in their transmission log submissions, then the link to viewing on other devices cannot be made in order to report this non-TV viewing As Broadcast. Users can check for the presence of BCIDs in bureaux systems by selecting the BCID field. This means that non-TV device viewing figures may be present for some programmes and not others for the same broadcaster. We are working to resolve these issues and to make these data available in the dashboard as soon as possible. I’m a BARB customer; what new data files are being produced and how do I access them? BARB is producing two new primary file outputs: A complete daily audience file of all online TV programmes, broken down by the most widely-used demographic groups. This file is called web database 2 (web db2). Programme average audiences can be calculated from this file. A daily respondent-level data file, with top programmes and broadcaster/player audiences calibrated. Unduplicated multiple-screen reach and time spent viewing can be calculated from this file, which is called the cross-platform panel viewing file (pvx). These files are available for BARB customers and all BARB-registered data-processing bureaux. Please ask your bureau for more information on which data it is making available for users. Why is smartphone viewing only available for all individuals in programme average audiences? Converting device ratings to people ratings requires measurement of how our panel members view BVOD services on different devices. We are evaluating how to generate a people-based measure of smartphone viewing. This could involve the use of router meters in our panel; we are currently testing router meters from two research companies. While we assess the viability of these new techniques, we can include programme average audience figures for smartphones alongside other screens for all individuals. We do this by assuming that each smartphone viewing session is viewed by an individual of unknown demography, i.e. one viewer-per-view. Smartphone viewing will not be included in multiple-screen reach and time spent viewing until we have a panel measurement of viewing on smartphones. How has the BARB universe changed with the launch of multiple-screen viewing figures? BARB’s universe has been private households in the UK with at least one TV set. We have extended the universe to include private households with a broadband connection and no TV set; we measure viewing on tablets and PCs in these homes. Broadband-only homes add approximately 3% to the universe. For continuity, users can still analyse viewing within the TV-household universe. For reference, BARB’s universe does not include student halls of residence, military bases, offices and prisons. What's the definition of total TV? Has this changed with the launch of multiple-screen viewing figures? The established definition of total TV will be called C7 TV set viewing (consolidated seven-day TV set viewing); for continuity, channel reach and time spent viewing will be published to this definition on BARB’s website, alongside a new definition of total TV. The new definition is called total three-screen viewing. This encompasses the new forms of viewing that BARB reports. Timeshift viewing on TV sets (either via a recording device or via a BVOD service) up to 28 days after broadcast. Viewing to programmes that haven’t featured in a linear schedule (i.e. BVOD viewing pre-broadcast, or BVOD-only programmes). Viewing on tablets and PCs. Viewing in private homes that don’t have a TV set but do have a broadband connection. Total three-screen viewing will be introduced at the same time as the launch of multiple-screen reach and time spent viewing. Users will have the flexibility to create their own definitions through analytics systems. Smartphones aren’t yet included in the new definition as we don’t have a panel measurement of how people watch on these devices. For reference, census data show that smartphones add approximately 0.25% to total viewing time. What is the impact of the new definition of total TV on reach? Total three-screen viewing, the new definition of total TV, includes homes that don’t have a TV set but do have a broadband connection. People in these homes are less likely to be TV viewers as they don’t have a TV set; we measure their viewing on tablets and PCs. There is an increase in the actual number of viewers when we include broadband-only homes in the universe. But this increase in the number of viewers is not as big as the increase in number of people in the universe; this is why the proportion of people viewing will be lower than in the previous definition of total TV. What is the difference between As Broadcast and As Viewed? Until now, BARB has reported programmes as being watched at the time they were broadcast, even if the viewing was timeshifted. This is called the As Broadcast method of reporting. The As Viewed method of reporting allocates viewing to the time it was actually watched. Multiple-screen reach and time spent viewing figures will be based on total three-screen viewing, the new definition of total TV, and will be reported on the BARB website using the As Viewed method. This is because they include timeshift viewing up to 28 days after broadcast, and we don’t want to slow down our reporting of reach and time spent viewing. We continue to use the As Broadcast method for reporting programme audiences in the dashboard on our website. We also use the As Broadcast method in the reporting of C7 TV set viewing (the previous definition of total TV which is available on the website for continuity purposes). Data-processing bureaux may allow analysis of viewing based on either definition. What is the new BARB gold standard? Gold standard refers to the calculation methodologies agreed by BARB. All the viewing figures we report are a result of implementing these gold standard methodologies. There is no change to the industry-agreed default position for the trading currency. This is consolidated seven-day commercial impacts on TV sets. We are changing the definition of total TV that’s used to report multiple-screen reach and time spent viewing. The new definition, total three-screen viewing, encompasses the new forms of viewing that BARB reports: tablets and PCs, non-linear programme box sets, 8-28 day catch-up and viewing in broadband-only homes. Why don't some BARB-reported channels have multiple-screen viewing figures? We can only produce multiple-screen viewing figures for BVOD services that have implemented software code to our specification; this is known as tagging. This software code generates the census data required from tablets, PCs and smartphones. We cannot collect census data from non-tagged BVOD services. Where channels are available to view through more than one BVOD service, we are only able to report multiple-screen viewing figures for the tagged service. For example, a channel with its own non-tagged BVOD service and which is also available through the Sky Go and Virgin services, will only have its multiple-screen viewing figures via Sky Go reported, as this is the only tagged service. We currently produce multiple-screen viewing figures for the following BVOD services: All4, BBC iPlayer, ITV Hub, My5, S4C Clic, Sky Go, STV Player and UKTV Play. I operate a BARB-reported channel with a BVOD service, how do I track multiple-screen viewing data? We produce multiple-screen viewing figures for BVOD services that have implemented software code to our specification. If you are interested in tagging your BVOD service in this way, please contact us. How much does BVOD viewing on tablets, PCs and smartphones add to TV set viewing? Collectively, time spent viewing BVOD services on tablets, PCs and smartphones adds approximately 1.3% to TV set viewing. This is an average across all programmes, some of which have a much greater proportion of their audiences watching on devices other than the TV set. What is non-linear viewing and where is it included? Broadcasters are increasingly making programmes available to watch on their BVOD services before (or without) linear broadcast. BARB can report audiences to non-linear programmes with the co-operation of the broadcaster. In these cases, non-linear viewing is included in total three-screen viewing, our new definition of total TV. See this BARB Explained for more information. Where is BVOD viewing that takes place via the TV set included? When a panel home watches a programme that was broadcast within the last 28 days on a TV set, this viewing is included in the programme average audience figures, even if they have watched through a BVOD service. This is because we use audio matching to identify which programmes are watched on a TV set. We can’t yet allocate timeshifted viewing to a BVOD service or to a recorded playback, except in Sky homes. See this BARB Explained for more information. We don’t yet report viewing to BVOD commercials on the TV set. Why is multiple-screen advertising campaign performance not available? The delivery of multiple-screen advertising campaign reach and frequency is dependent on generating content identifying tags from BVOD-served commercials. The serving of ads is a different process to the serving of programmes, and requires a separate software implementation. At present, we are working with broadcasters on generating these tags from commercials. Data from these tests will be used to review our proposed methodology. Kantar Media will then develop and test the methodology, prior to a period of user acceptance testing and stakeholder review. The timetable to delivery is still being finalised. How does BARB define viewability on PCs, tablets and smartphones? BARB’s principal convention is that a television programme or commercial has been seen when it is watched at normal speed, with at least one panel member registered as being in the room. Importantly, we deliver duration-based metrics. These conventions guide us, as we plan to report viewing of online TV delivered on TV sets. This BARB Explained explains our approach to the issue of whether programmes and commercials are visible on the screen. Is BARB's online measurement vulnerable to click fraud? We commission independent auditing to reinforce the trustworthiness of our published viewing data. The audit process verifies that data we receive has removed three types of activity: a) viewing from IP addresses that are located on the business premises of the broadcasters whose programmes are being measured, b) non-human traffic, and c) traffic from outside the UK. The audit process is conducted by ABC (Audit Bureau of Circulations).
