Systems, methods, and apparatus to monitor media presentations

1. A method to monitor media presentations, the method comprising:

identifying a media presentation device associated with a Domain Name Service (DNS) query based on a public Internet Protocol (IP) address that originated the DNS query and a destination address of the DNS query;

identifying a media source based on a domain name requested in the DNS query;

attempting to identify media presented in association with the DNS query based on at least one of tagging data and metering data;

crediting, with a processor, a panelist associated with the media presentation device with exposure to the identified media from the media source via the media presentation device when the media is identified; and

crediting, with the processor, the panelist associated with the media presentation device with exposure to media from the media source via the media presentation device when the media is not identified.

2. The method as described in claim 1 , further comprising:

identifying a media presentation start event and a media presentation stop event based on the metering data; and

crediting the panelist with exposure to the media for a duration of time between the media presentation start event and the media presentation stop event.

3. The method as described in claim 1 , wherein the metering data comprises an identifier of the presented media.

4. The method as described in claim 3 , wherein the identifier comprises at least one of a code, a signature, or metadata of the identified media.

5. The method as described in claim 3 , wherein the metering data does not enable identification of the media source.

6. The method as described in claim 3 , further comprising receiving the metering data from a meter installed at a media presentation location.

7. The method as described in claim 1 , wherein the tagging data comprises an identifier of the presented media.

8. The method as described in claim 1 , wherein the tagging data comprises metadata associated with the presented media.

9. An apparatus to monitor media presentations, the apparatus comprising:

at least two Domain Name Service (DNS) query processors to receive DNS queries from respective media presentation devices associated with a public Internet protocol (IP) address, the DNS queries identifying the public IP address, an address of the respective DNS query processor receiving the DNS query, and a requested domain name associated with a media provider;

a metering data receiver to receive metering data from a meter installed in proximity to the media presentation devices, the metering data to identify the media presented by the media presentation devices;

a tag data receiver to receive tagging data from the media presentation devices, the tagging data identifying the media presented by the media presentation devices; and

a correlator to correlate the DNS queries with at least one of the metering data and the tagging data to identify media presented by the respective media presentation devices and the media provider providing the media.

10. The apparatus as described in claim 9 , further comprising a timestamper to timestamp at least one of the received DNS queries, the metering data, and the tagging data.

11. The apparatus as described in claim 9 , further comprising a registrar to:

associate the at least two DNS query processors with respective ones of the media presentation devices; and

associate a record of the public IP address with the media presentation device.

12. The apparatus as described in claim 9 , further comprising an audience measurement processor to credit a respective one of the media presentation devices with exposure to media from the media provider.

13. The apparatus as described in claim 12 , further comprising a reporter to generates reports indicative of media exposure metrics based on the credited exposure.

14. A machine-readable storage medium comprising instructions which, when executed, cause a machine to at least:

identify a media presentation device associated with a Domain Name Service (DNS) query based on a public Internet Protocol (IP) address that originated the DNS query and a destination address of the DNS query;

identify a media source based on a domain name requested in the DNS query;

attempt to identify media presented in association with the DNS query based on at least one of tagging data and metering data;

credit a panelist associated with the media presentation device with exposure to the identified media from the media source via the media presentation device when the media is identified; and

credit the panelist associated with the media presentation device with exposure to media from the media source via the media presentation device when the media is not identified.

15. The machine-readable storage medium as described in claim 14 , further comprising instructions which, when executed, cause the machine to at least:

identify a media presentation start event and a media presentation stop event based on the metering data; and

credit the panelist with exposure to the media for a duration of time between the media presentation start event and the media presentation stop event.

16. The machine-readable storage medium as described in claim 14 , wherein the metering data comprises an identifier of the presented media.

17. The machine-readable storage medium as described in claim 16 , wherein the identifier comprises at least one of a code, a signature, or metadata of the identified media.

18. The machine-readable storage medium as described in claim 16 , wherein the metering data does not enable identification of the media source.

19. The machine-readable storage medium as described in claim 16 , further comprising instructions which, when executed, cause the machine to receive the metering data from a meter installed at a media presentation location.

20. The machine-readable storage medium as described in claim 14 , wherein the tagging data comprises an identifier of the presented media.
