Abstract: Methods and apparatus to monitor media presentations are disclosed. Disclosed example apparatus include memory, instructions, and at least one processor to execute the instructions to at least receive demographic information from a user, transmit the demographic information to a central facility, cause storage of 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, access the consent identifier from the pasteboard, present media, generate monitoring information if the consent identifier permits collection of monitoring information, not generate monitoring information if the consent identifier does not permit the collection of the monitoring information, and transmit the monitoring information to the central facility.

Abstract: Disclosed examples include logging impression records corresponding to pingback messages received in network communications from a client device, ones of the pingback messages corresponding to portions of media presented at the client device; determining a duration impression for the media based on the impression records; dividing the duration impression based on media types corresponding to the portions of the media presented at the client device; and determining demographic characteristics for ones of the media types in the portions of the media.

Abstract: Methods and apparatus to collect distributed user information for media impressions and search terms are disclosed. An example method includes accessing, from a media device, a first identifier and a search term at a first server, the first identifier corresponding to at least one of the media device or a user of the media device, the search term associated with a search request, generating a second identifier based on the first identifier, sending the second identifier and the search term from the first server to a data collection server to facilitate the data collection server to logging the search request, and receiving user information associated with the search request from a database proprietor based on the second identifier.

Abstract: Methods and apparatus to measure exposure to streaming media are disclosed. An example apparatus includes for measurement of exposure to streaming media includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to: access metadata identifying media presented to a user, and cookie data, the metadata and the cookie data provided by a client device; determine whether the cookie data identifies the user to a database proprietor; in response to a determination that the cookie data does not identify the user to the database proprietor, send a redirect message instructing the client device to retransmit the metadata to a next-hop location; and in response to a determination that the cookie data does identify the user to the database proprietor, provide the metadata and a user identifier to a central facility.

Abstract: An example system includes: at least one memory; programmable circuitry; and instructions to cause the programmable circuitry to: cache a first ordered list of internet protocol (IP) addresses in a domain name system (DNS) cache; cache a second ordered list of IP addresses in the DNS cache; access a first server identifier from a first server associated with the first ordered set of IP addresses; access a second server identifier from a second server associated with the second ordered list of IP addresses; hash the first and second server identifiers to generate a user identifier; and store the user identifier as a cookie.

Abstract: Example methods, apparatus, systems and articles of manufacture to facilitate local time-based digital audio measurement are disclosed. In examples disclosed herein, a hello ping may be received from a media player. The media player may be associated with a location based on the hello ping. The media player may be associated with a time offset based on the location. A configuration file may be generated to include the location and the time offset.

Abstract: An example apparatus includes memory and at least one processor to execute first instructions. The first instructions cause the at least one processor to send second instructions from a first server to a client device. The second instructions cause the client device to send first messages to a second server at intervals based on a presentation of media via the client device. The second instructions cause the client device to send a second message to the second server based on a skip request associated with the presentation of the media via the client device. The first instructions further cause the at least one processor to log impressions corresponding to the first messages and the second message, and to determine a duration impression for the media based on the logged impressions. The duration impression identifies the portions of the media that were presented at the client device.
