Methods and apparatus to monitor media presentations

1. A media device comprising:

means for receiving demographic information from a user;

first means for transmitting the demographic information to a central facility;

means for storing a consent identifier in a pasteboard of the media device, the consent identifier accessible to a first instrumented application and a second instrumented application executed in a sandbox environment, the consent identifier to indicate to the first instrumented application and the second instrumented application that monitoring is allowed;

means for accessing the consent identifier from the pasteboard;

means for presenting media;

means for generating monitoring information if the consent identifier permits collection of monitoring information;

means for not generating monitoring information if the consent identifier does not permit the collection of the monitoring information; and

second means for transmitting the monitoring information to the central facility.

2. The media device as described in claim 1 , further including means to store a panelist identifier identifying a panelist associated with the media device.

3. The media device as described in claim 2 , further including means to access the panelist identifier from the central facility.

4. The media device as described in claim 2 , further including means to determine the panelist identifier.

5. The media device as described in claim 2 , wherein the panelist identifier is based on user-identifying information received from the panelist.

6. The media device as described in claim 2 , wherein the panelist identifier is encrypted.

7. The media device as described in claim 1 , wherein the means for presenting media is to present media via at least one of a game, a media presenter, or a news presenter.

8. An apparatus for monitoring a media device, the apparatus comprising:

means for providing a software development kit to an application developer, the means for providing to enable the application developer to create a monitoring enabled application to be executed at the media device;

means for transmitting a panelist identifier in response to a request from a registrar executed by the media device, the registrar separate from the monitoring enabled application, the registrar to store a consent identifier in a pasteboard of the media device, the request including demographic information associated with a user of the media device, the panelist identifier stored in the pasteboard of the media device by the registrar executed at the media device and accessible to multiple monitoring enabled applications on the media device, the monitoring enabled application to collect at least one of application monitoring data or media monitoring data if the consent identifier is in the pasteboard and to disable collection of the at least one of the application monitoring data or the media monitoring data if the consent identifier is not in the pasteboard, the registrar to delete the consent identifier and to leave the panelist identifier in a data store associated with the at least one of the application monitoring data or the media monitoring data; and

means for collecting the at least one of the application monitoring data or the media monitoring data from the monitoring enabled application.

9. The apparatus as described in claim 8 , wherein the means for transmitting is to generate the panelist identifier.

10. The apparatus as described in claim 8 , further including means for storing the at least one of the application monitoring data or the media monitoring data collected by the means for collecting.

11. The apparatus as described in claim 10 , wherein the means for storing is to store the demographic information received by the means for transmitting.

12. The apparatus as described in claim 8 , further including means for generating a report representing the at least one of the application monitoring data or the media monitoring data in connection with the demographic information.

13. The apparatus as described in claim 8 , further including means for receiving the demographic information and the at least one of the application monitoring data or the media monitoring data from the monitoring enabled application.

14. The apparatus as described in claim 8 , wherein the monitoring enabled application generates the at least one of the application monitoring data or the media monitoring data when the consent identifier is deleted.

15. An apparatus for monitoring a media device, the apparatus comprising:

means for collecting demographic information from a user with a registrar of a media device;

means for transmitting the demographic information to a central facility from the registrar; and

means for storing a panelist identifier identifying the user in a shared memory of the media device, the panelist identifier accessible to a first monitoring-enabled application and a second monitoring-enabled application, the first monitoring-enabled application and the second monitoring-enabled application separate from the registrar, the panelist identifier to be retrieved by the first monitoring-enabled application, the first monitoring-enabled application to present media, the first monitoring-enabled application to collect monitoring information if the panelist identifier is in the shared memory and to disable collection of media monitoring information if the panelist identifier is not in the shared memory.

16. The apparatus as described in claim 15 , further including means for requesting permission from the user to enable monitoring.

17. The apparatus as described in claim 16 , further including:

means for storing, if permission is received, a consent identifier enabling the collection of the media monitoring information by the first monitoring-enabled application and the second monitoring-enabled application; and

means for ensuring, if permission is not received, the consent identifier is not stored.

18. The apparatus as described in claim 17 , wherein a consent indicator to enable monitoring is the panelist identifier.

19. The apparatus as described in claim 15 , wherein the panelist identifier is based on the demographic information.

20. The apparatus as described in claim 15 , wherein the panelist identifier is requested from the central facility.
