Panelist-Site Metering in Conjunction with Streaming-Provider Data as a Basis to Facilitate Measurement of Live-Stream Exposure

A method for use of metering as a basis to measure media exposure, the method comprising:

• using meters at panelist sites of a panel in a market to detect instances of panelist-site playout of a live-stream broadcast, and establishing one or more preliminary media-exposure measurements based on the detected instances of panelist-site playout;
• obtaining streaming-provider data that indicates instances of streaming of the broadcast for playout in the market;
• generating a market-wide scaling factor by at least (a) extrapolating the detected instances of panelist-site playout to a population of the market to estimate a market-wide playout total of time increments of playout of the broadcast, (b) establishing from the streaming-provider data a market-wide streaming total of time increments of streaming of the broadcast for playout, and (c) generating the market-wide scaling factor based on a ratio of the market-wide streaming total number to the market-wide playout total;
• generating a panel-specific scaling factor specific to the panel in the market, by at least (a) determining, based on the detected instances of panelist-site playout of the broadcast, a panel-specific playout total of time increments of playout at panelist sites of the panel, (b) filtering the streaming-provider data to establish a panel-specific streaming total of time increments of streaming of the broadcast to the panelist sites of the panel, and (c) establishing the panel-specific scaling factor based on a ratio of the panel-specific streaming total to the panel-specific playout total;
• and
• applying at least the market-wide scaling factor and panel-specific scaling factor to the one or more preliminary media-exposure measurements, to establish one or more adjusted media-exposure measurements.

A media-exposure-measurement system comprising:

• a plurality of meters at panelist sites of a panel in a market, wherein the meters are configured to detect instances of playout of media at the panelist sites;
• at least one processor;
• non-transitory data storage;
• and
• program instructions stored in the non-transitory data storage and executable by the at least one processor to carry out operations based on the meters detecting instances of panelist-site playout of a live-stream broadcast:
• receiving, from the meters at panelist sites of the panel, reports of detected instances of panelist-site playout of a live-stream broadcast, and establishing one or more preliminary media-exposure measurements based on the detected instances of panelist-site playout,
• obtaining streaming-provider data that indicates instances of streaming of the broadcast for playout in the market,
• generating a market-wide scaling factor based on a ratio of (i) a market-wide total time of streaming of the broadcast in the market according to the streaming-provider data to (ii) an estimated market-wide total time of playout of the broadcast in the market based on the detected instances of panelist-site playout,
• generating a panel-specific scaling factor specific to the panel in the market, based on a ratio of (i) a panel-specific total time of streaming of the broadcast to panelist sites of the panel to (ii) an estimated panel-specific total time of playout of the broadcast at panelist sites of the panel, and
• applying at least the market-wide scaling factor and panel-specific scaling factor to the one or more preliminary media-exposure measurements, to establish one or more adjusted media-exposure measurements.
