About OzTAM ratings
OzTAM TV ratings are audience estimates based on actual viewing behaviour in 5,250 panel homes in Australia's five mainland capital cities - Sydney, Melbourne, Brisbane, Adelaide and Perth - and 2,120 homes nationally for subscription television.
OzTAM’s TV ratings service provider, Nielsen TAM, collects and produces TV ratings data on OzTAM’s behalf.
Households are recruited to OzTAM’s television audience measurement panel via a large-scale Establishment Survey that defines the population to be represented and its characteristics. In terms of panel size relative to the overall population, OzTAM’s panel is among the world’s largest.
OzTAM uses a sophisticated people metering system called Unitam which captures viewing to all broadcast television channels on all TV sets in panel homes.
