Abstract: Examples to determine media impressions using distributed demographic information are disclosed. An example apparatus includes a communication interface to receive a network communication at an impression monitor system based on a login event at a client device, the login event associated with an Internet-based service of a first Internet domain different from a second Internet domain of the impression monitor system. The example communication interface also sends a response to the client device, the response to cause the client device to include first and second cookie identifiers in a login reporting message and to send the login reporting message to a computer of a database proprietor that provides the Internet-based service, the first cookie identifier associated with the first Internet domain of the Internet-based service, and the second cookie identifier associated with the second Internet domain of the impression monitor system.

Abstract: An example involves, in response to a first request from a first client device, logging a first impression in association with a first identifier corresponding to media accessed by the first client device that generated the first request, and sending a communication to the first client device. The communication is to cause the first client device to send the first identifier to a database proprietor in association with a cookie identifier of the first client device. Second impressions are logged in response to second requests received from second client devices. The second impressions are associated with the first identifier and correspond to access to the media by the second client devices. A report is generated based on the first impression and corresponding first demographic information from the database proprietor, and based on the second impressions and corresponding second demographic information from an audience measurement entity different from the database proprietor.

Abstract: An example apparatus includes a data parser to extract an identifier and a cookie identifier from a message received at a first server of a first Internet domain from a client device, the cookie identifier associated with the first Internet domain, the identifier identifying at least one of the client device or a user of the client device to a second server in a second Internet domain outside the first Internet domain, a memory to store the identifier in association with the cookie identifier in an identifier-to-cookie map, a processor to associate demographic information corresponding to the identifier with an impression logged at the first server in association with the cookie identifier, the associating based on accessing the memory to identify that the cookie map stores the identifier with the cookie identifier, and a report generator to send the demographic information to the second server.

Abstract: Methods and apparatus to determine media impressions using distributed demographic information are disclosed. An method includes sending to a client computer, via a processor serving a first internet domain, a response to a first request, the first request sent to the first internet domain and indicative of access to media at the client computer, the response to instruct the client computer to send a second request to an intermediary serving a sub-domain of a second internet domain, the second request to be indicative of the access to the media at the client computer, wherein the intermediary is to transmit first data about the second request to a data collection server of an audience measurement entity and second data about the second request to an entity of the second internet domain and logging an impression of the media.

Abstract: Examples to determine media impressions using distributed demographic information are disclosed. Some disclosed example methods involve sending a request to an impression monitor system in response to detecting a login event at a client device. The login event is associated with an Internet-based service of a first Internet domain different from a second Internet domain of the impression monitor system. Such disclosed example methods also involve sending a login reporting message to a database proprietor that provides the Internet-based service. The login reporting message including first and second cookie identifiers. The first cookie identifier is associated with the first Internet domain of the Internet-based service, and the second cookie identifier is associated with the second Internet domain of the impression monitor system.

Abstract: An example method to monitor media exposure involves receiving, at a first internet domain, a first request from a client computer, the first request indicative of access to the media at the client computer. The example method also involves determining if the client computer is known. If the client computer is not known, a response is sent from the first internet domain to the client computer, the response to instruct the client computer to send a second request to a second internet domain, the second request to be indicative of access to the media at the client computer. If the client computer is known, an impression of the media is logged.

Abstract: An example involves, in response to a first request from a first client device, logging a first impression in association with a first identifier corresponding to media accessed by the first client device that generated the first request, and sending a communication to the first client device. The communication is to cause the first client device to send the first identifier to a database proprietor in association with a cookie identifier of the first client device. Second impressions are logged in response to second requests received from second client devices. The second impressions are associated with the first identifier and correspond to access to the media by the second client devices. A report is generated based on the first impression and corresponding first demographic information from the database proprietor, and based on the second impressions and corresponding second demographic information from an audience measurement entity different from the database proprietor.
