Abstract: Methods and apparatus to measure exposure to streaming media are disclosed. An example method includes detecting an ID3 tag associated with streaming media presented at a client device. Data is extracted from a first field of the ID3 tag. The data from the first field of the ID3 tag is processed to generate a first request directed to a first internet domain, the first internet domain based on the data, the first request including a media identifier from a second field of the ID3 tag, the second field of the ID3 tag separate from the first field of the ID3 tag, the media identifier identifying the streaming media. In response to the detection of the ID3 tag, the first request is sent from the client device to the first internet domain.

Abstract: Methods and apparatus to measure exposure to streaming media are disclosed. An example method includes detecting an ID3 tag associated with streaming media presented at a client device. A first request is sent from the client device to a first internet domain, the first request identifying the streaming media. A redirection message is received from the first internet domain. In response to the redirection message, a second request is sent to a second internet domain specified by the redirection message. A cookie is provided identifying the client device to the second internet domain.

Abstract: An example method includes facilitating installation of a data collector on a media device; collecting, via the data collector, a media identifier indicative of media presented at the media device; encrypting a user identifier that identifies the user of the media device, the encrypting of the user identifier based on a first encryption key corresponding to a first database proprietor having first user information associated with the user identifier; encrypting a device identifier that identifies the media device, the encrypting of the device identifier based on a second encryption key corresponding to a second database proprietor having second user information associated with the device identifier; sending the media identifier to a data collection server; sending the encrypted user identifier to a second server associated with the first database proprietor; and sending the encrypted device identifier to a third server associated with the second database proprietor.

Abstract: An example method includes receiving a media identifier and an impression identifier from a device, the media identifier being indicative of media presented at the device; receiving the impression identifier in association with first user information from a first database proprietor as a result of the first database proprietor obtaining a first identifier sent from the device, the first identifier identifying at least one of the device or a user; receiving the impression identifier in association with second user information from a second database proprietor as a result of the second database proprietor obtaining a second identifier sent from the device, the second identifier identifying at least one of the device or the user; identifying the first and second user information as associated with a same user based on the impression identifier; and associating the first and second user information with the media identifier.

Abstract: Methods and apparatus to monitor media presentations are disclosed. An example method includes storing a consent indicator at a central facility in connection with a user of a media device; and, when monitoring data representative of an exposure to media of the user is received, determining a value of the consent indicator; when the value indicates that the user is an opted-in user, storing a first type of exposure indication in association with the first media, the first type of exposure indication to include personally identifying information associated with the user stored in connection with the first media; and when the value indicates that the user is an opted-out user, storing a second type of exposure indication in association with the first media, the second type of exposure indication to omit the personal identifying information associated with the user from being stored in connection with the first media.

Abstract: Methods, apparatus, systems and articles of manufacture to monitor media presentations are disclosed. An example method includes collecting demographic information from a user. The demographic information is transmitted to a central facility. A panelist identifier identifying the user is generated. The panelist identifier is stored in a shared memory of the media device, the panelist identifier to be retrieved by a monitoring enabled application, the monitoring enabled application to collect monitoring information if the panelist identifier is in the shared memory and to disable collection of the media monitoring information if the panelist identifier is not in the shared memory.
