Portable multi-purpose audience measurement systems, apparatus and methods

At least one storage device comprising computer readable instructions that, when executed, cause at least one processor to at least:

• cause meter software to be provided to a first compute device, the meter software executable by the first compute device to monitor media presentation related activities of the first compute device, wherein the instructions are to cause the at least one processor to cause the meter software to be provided to the compute device by causing a message to be sent to the compute device, and conditioning download of the meter software to the compute device on receipt of a response to the message;
• obtain demographic data of a user associated with the first compute device, the demographic data from a second compute device different from the first compute device;
• obtain meter data from the first compute device, the meter data generated by the meter software;
• and
• associate the meter data with the demographic data.

A method comprising:

• providing meter software to a compute device, the meter software executable by the compute device to monitor use of the compute device in association with a presentation of media, wherein the providing of the meter software to the compute device includes sending a message to the compute device, and conditioning download of the meter software to the compute device on receipt of a response to the message;
• obtaining, by executing an instruction with a processor, demographic data of a user associated with the compute device, the demographic data from a source different from the compute device;
• receiving meter data from the compute device, the meter data generated by the meter software;
• and
• associating, by executing an instruction with the processor, the meter data with the demographic data.
