Abstract: Methods and apparatus to determine media impressions using distributed demographic information are disclosed.

Abstract: A disclosed example to monitor access to media includes; a communication interface to send a uniform resource locator (URL) scrape instruction to a client computer in response to a first request from the client computer, the first request indicative of access to the media at the client computer; a processor in circuit with the communication interface; and memory including machine readable instructions that, when executed by the processor, cause the processor to: provide the URL scrape instruction to the communication interface when a URL of a host website of the media is not obtainable by the processor from the first request, the URL scrape instruction to cause the client computer to: (1) read the URL of the host website from an address bar of a web browser at the client computer, and (2) send the URL of the host website to a server; and store a logged impression of the media in association with the URL of the host website from the client computer.

Abstract: Computer implemented methods and systems select television inventory units for a television advertising campaign. The method includes: (a) receiving information identifying (i) a target television audience, (ii) a plurality of television inventory units and a given price for each television inventory unit, and (iii) a budget for the television advertising campaign; (b) determining the probability of the target television audience viewing each of the plurality of television inventory units based on historical television viewing data; (c) for feasible combinations of television inventory units meeting the budget for the television advertising campaign, determining an expected target television audience reach based on the probabilities determined in step (b); and (d) selecting the feasible combination of television inventory units providing the greatest television audience reach for the television advertising campaign. The methods and systems can also be used for other media advertising campaigns including, e.g.

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: 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 are disclosed. An example method includes determining an exposure of first media, wherein the exposure occurs after a cookie identifier is received at a computing device, wherein the cookie identifier is received from a database proprietor, determining a first panelist identifier associated with the exposure based on the cookie identifier, determining a second panelist identifier associated with the exposure based on a determination of a user identity by a panelist meter associated with the computing device, determining an adjustment factor by comparing the first panelist identifier and the second panelist identifier, determining a number of impressions of second media from data logged by the database proprietor, the data logged in response to requests transmitted to the database proprietor in response to clients accessing the second media, and applying the adjustment factor to the number of impressions to determine an adjusted number of impressions.

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.
