A method may include receiving radio station data associated with multiple radio stations from one or more radio station providers and filtering the radio stations based at least in part on playback availability. Playback availability may include a broadcast right associated with the one or more radio station providers. The method may also include removing duplicate radio stations and supplying a searchable radio station directory to a platform or a client device.

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.

Methods, apparatus, systems, and articles of manufacture are disclosed to assign demographic distribution data to digital television ratings. An example apparatus includes factor generation circuitry to calculate a demographic adjustment factor based on digital probability distribution function (PDF) (digital-PDF) impressions and linear PDF (linear-PDF) impressions. The example factor generation circuitry is also configured to calculate a device adjustment factor based on historical calibrated demographic digital impressions and historical computed demographic digital impressions. The example apparatus further includes adjustment calculation circuitry to determine digital demographic impressions by applying the demographic adjustment factor to the current raw digital census impressions. The example adjustment calculation circuitry is also configured to determine digital device-demographic impressions by applying the device adjustment factor to the digital demographic impressions.
