Abstract: A method of automatically logging and collating geographic viewing data for broadcast television comprises providing a media device with a reporting means arranged to generate viewing data detailing a channel being watched automatically once received by the media device, and to transmit that viewing data to a server using a transport protocol, so forming transmitted viewing data comprising the generated viewing data and one or more headers associated with the transport protocol; processing the transmitted viewing data to identify information comprising at least one of: transmission metadata from a transmitter which transmitted the channel to the media device; and an external IP address of the media device; matching at least one of the viewing-data, the transmission metadata, and the external IP address to external data; and determining the geographical location from which the viewing-data originated using at least one of the identified information and the matched external data.
