Portable multi-purpose audience measurement system

摘要

As disclosed herein, media metering functionality may be imparted to a panelists device that was not previously capable of media metering. According to one example, a method comprises collecting demographic data of a user, including a phone number for a mobile device, via a website associated with an information gathering entity; sending a message to the mobile device, wherein the sent message, when responded to, results in a downloading of a metering software module to the mobile device; and receiving, from the mobile device and at a system associated with the information gathering entity, information indicative of events associated with the use of the mobile device, wherein the received information and the demographic data are associated during processing by the system associated with the information gathering entity.
