A computer-implemented method of using video program viewer interaction data that has been loaded to a media measurement database as input to a measurement engine which then calculates Linear, DVR, and VOD asset viewing activity at three levels: (a) Video Program, (b) Video Program Airing, (c) Video Program Airing Segment, where each level provides summary metrics for groupings of Demographic, Geographic, and/or Device Characteristic, and also second-by-second viewing metrics, including counting advertising impressions, within the Demographic, Geographic, Device groupings. System also accounts for reduced value of ad viewing when viewer is using trick plays or when viewer delays viewing recorded content. Together these metrics provide detailed information on customer viewing behavior which can be used to drive business decisions for service providers, advertisers and content producers. Additionally, a viewing histogram analysis is produced.

Methods, apparatus, systems and articles of manufacture to estimate ratings for media assets using social media are disclosed. An example method includes accessing media exposure data and social media activity data corresponding to a plurality of media assets in a media bundle, the media assets included in the media bundle having audience demographics that overlap with a first media asset, determining a first credibility factor for the first media asset and average exposure for social media activity count values for respective ones of the media assets in the media bundle based on the media exposure data and the social media activity data, and applying the first credibility factor to an average exposure per social media activity count value determined for the first media asset to estimate the ratings for the first media asset.

A system that allows for performance indicators such as a success rate of a broadcast message or latency between a sender and mobile station of a broadcast message, during emergency broadcasts to a wireless transmit/receive unit, such as a mobile phone.

Methods, apparatus, systems and articles of manufacture to update audio sensor configuration are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to: in response to detection of an update to audio sensor configuration, identify a plurality of potential audio sensor configurations to be used to receive audio, select respective ones of the identified potential audio sensor configurations for testing, determine signal-to-noise ratios corresponding to each of the selected ones of the potential audio sensor configurations, select the greatest signal-to-noise ratio of the signal-to-noise ratios, compare the greatest signal-to-noise ratio value and a noise ratio change threshold, and in response to the selected greatest signal-to-noise ratio value exceeding the noise ratio change threshold, update a configuration memory to cause use of the potential audio sensor configuration corresponding to the selected greatest signal-to-noise ratio.

Disclosed example apparatus to determine volume of switching (VoS) among television programs examine first viewing data associated with a first time period and second viewing data associated with a second time period to identify a first set of panelists represented in both the first and second viewing data; in response to a size of the first set of panelists satisfying both first and second thresholds, estimate the VoS based on a first subset of the first viewing data and a second subset of the second viewing data associated with the first set of panelists; and in response to the size of the first set of panelists satisfying the first but not the second threshold, estimate the VoS based on the first and second subsets, and a third subset of the first viewing data and a fourth subset of the second viewing data associated with a second set of panelists.

Disclosed example audience measurement apparatus determine a first audience metric based on set-top box return path tuning data obtained from set-top boxes located in a first geographic area; determine a second audience metric from a portion of audience measurement data corresponding to a second geographic area, the portion of the audience measurement data associated with monitored sites in the second geographic area having second set-top box characteristics that correspond with first set-top box characteristics of the set-top boxes located in the first geographic area; determine ratios of (i) respective first audience metrics determined for respective demographic stratifications to (ii) corresponding second audience metrics determined for the respective demographic stratifications; and combine the ratios after multiplication with third audience metrics determined, for the respective demographic stratifications, from the audience measurement data to determine an audience exposure metric that estimates exposure to media in the first geographic area.
