Abstract

Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a ratings calculator to calculate an initial local rating for media provided in a first geographic area based on local return path data (RPD) tuning information obtained from local RPD devices in subscriber households in the first geographic area. The subscriber households subscribe to a content provider that provides the media through the local RPD devices. The apparatus further includes a calibration factor calculator to calculate a nonsubscriber calibration factor based on a first panelist rating for the media corresponding to a first subset of panelist households that do not subscribe to the content provider. The ratings calculator modifies the initial local rating based on the nonsubscriber calibration factor to calculate a final local rating for the media in the first geographic area.

First claim

What is claimed is:

1. An electronic apparatus for calculating ratings for media, the electronic apparatus comprising:
a communications interface to receive (1) local return path data (RPD) tuning information obtained from local RPD devices in subscriber households in a first geographic area and (2) panel tuning information obtained from metering devices in panelist households in a second geographic area, wherein the panel tuning information includes an indication of the media accessed via associated media devices and an indication of whether the associated media devices are capable of reporting RPD tuning information;
a ratings calculator to calculate an initial local rating for the media provided in the first geographic area based on the local RPD tuning information, wherein the subscriber households subscribe to a content provider that provides the media through the local RPD devices; and
a calibration factor calculator to:
calculate a nonsubscriber calibration factor based on a first panelist rating for the media provided in the second geographic area, the first panelist rating corresponding to a first subset of the panelist households that do not subscribe to the content provider, the first panelist rating based on the panel tuning information associated with the media delivered to the first subset of the panelist households via respective ones of the associated media devices for which RPD tuning information is not available; and
calculate a subscriber calibration factor based on a second panelist rating for the media provided in the second geographic area, the second panelist rating corresponding to a second subset of the panelist households that subscribe to the content provider, the second panelist rating based on the panel tuning information associated with the media delivered to the second subset of the panelist households via respective ones of the associated media devices for which RPD tuning information is not available, the ratings calculator to modify the initial local rating based on the nonsubscriber calibration factor and the subscriber calibration factor to calculate a final local rating for the media in the first geographic area.

2. The apparatus as defined in claim 1 , wherein the final local rating is based on a multiplication of the initial local rating and one plus the subscriber calibration factor.

3. The apparatus as defined in claim 1 , wherein the second geographic area is larger than the first geographic area, the second geographic area containing the first geographic area.

4. The apparatus as defined in claim 3 , further including a demographic comparator to assign weights to the panelist households in the second geographic area to be demographically representative of a population of the first geographic area.

5. The apparatus as defined in claim 3 , wherein the ratings calculator is to determine a regional RPD-based rating for the media provided in the second geographic area based on regional RPD tuning information obtained from regional RPD devices associated with subscriber households in the second geographic area, the calibration factor calculator to calculate the nonsubscriber calibration factor as a ratio of the first panelist rating to the regional RPD-based rating.

6. The apparatus as defined in claim 5 , wherein the final local rating is based on a multiplication of the initial local rating, the nonsubscriber calibration factor, and a nonsubscriber penetration, the nonsubscriber penetration corresponding to one minus a percentage of the subscriber households in the first geographic area relative to all households in the first geographic area.

7. The apparatus as defined in claim 1 , wherein the ratings calculator is to calculate an adjusted local rating based on a partial coverage of the media in the first geographic area, and to calculate the final local rating based on the adjusted local rating.

8. The apparatus as defined in claim 1 , wherein the second subset of the panelist households include RPD devices that generate RPD tuning information transmitted to the communications interface separate from the panel tuning information.

9. A non-transitory computer readable medium comprising instructions that, when executed by a processor, cause a machine to at least:
retrieve local return path data (RPD) tuning information from a RPD tuning information database, the local RPD tuning information obtained from local RFD devices in subscriber households in a first geographic area;
retrieve panel tuning information from a panel tuning information database, the panel tuning information obtained from metering devices in panelist households in a second geographic area, wherein the panel tuning information includes an indication of media accessed via associated media devices and an indication of whether the associated media devices are capable of reporting RPD tuning information;
determine an initial local rating for the media provided in the first geographic area based on the local RPD tuning information, wherein the subscriber households subscribe to a content provider that provides the media through the local RPD devices;
calculate a nonsubscriber calibration factor based on a first panelist rating for the media provided in the second geographic area, the first panelist rating corresponding to a first subset of the panelist households that do not subscribe to the content provider, the first panelist rating based on the panel tuning information associated with the media delivered to the first subset of the panelist households via respective ones of the associated media devices for which RFD tuning information is not available;
calculate a subscriber calibration factor based on a second panelist rating for the media provided in the second geographic area, the second panelist rating corresponding to a second subset of the panelist households that subscribe to the content provider, the second panelist rating based on the panel tuning information associated with the media delivered to the second subset of the panelist households via respective ones of the associated media devices for which RPD tuning information is not available; and
modify the initial local rating based on the nonsubscriber calibration factor and the subscriber calibration factor to calculate a final local rating for the media in the first geographic area.

10. The non-transitory computer readable medium as defined in claim 9 , wherein the final local rating is based on a multiplication of the initial local rating and one plus the subscriber calibration factor.

11. The non-transitory computer readable medium as defined in claim 10 , wherein the second geographic area is larger than the first geographic area, the second geographic area containing the first geographic area.

12. The non-transitory computer readable medium as defined in claim 11 , wherein the instructions further cause the machine to assign weights to the panelist households in the second geographic area to be demographically representative of a population of the first geographic area.

13. The non-transitory computer readable medium as defined in claim 11 , wherein the instructions further cause the machine to:
determine a regional RPD-based rating for the media provided in the second geographic area based on regional RPD tuning information obtained from regional RPD devices associated with subscriber households in the second geographic area; and
calculate the nonsubscriber calibration factor as a ratio of the first panelist rating to the regional RPD-based rating.

14. The non-transitory computer readable medium as defined in claim 9 , wherein the second subset of the panelist househo
