Any 3rd Party organization that measures and reports audience activity on the Internet across entities in a consistent manner. Traditionally, these organizations have primarily used a sample or panel of users (or households) who are recruited and tracked using software meters or other automated techniques. Due to the use of meters, Web-site or property user identification techniques such as cookies are not necessary. A strength of these organizations is the ability to attribute audience activity to users and the known demography of users in a panel or some other user-attributed data-source. Some syndicated measurement organizations may also use a hybrid approach (for instance, measurements that result from linking census-based data with data from a sampling approach that supplies demography).
