Abstract: Methods and apparatus to collect impressions associated with over-the-top media devices are disclosed. Example disclosed methods involve receiving, at a first Internet domain, a first request from a first client device, the first request including a client device identifier associated with a second client device, and associating the client device identifier with demographics at the first Internet domain, the demographics corresponding to a user of the first client device. Example disclosed methods involve receiving, at the first Internet domain, a second request from the second client device, the second request indicative of media accessed at the second client device, and storing an impression of the media at the first Internet domain by associating a media identifier obtained from the second request with the demographics based on the same client device identifier being associated with the media identifier in the second request and being associated with the demographics.

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.
