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, and OzTAM samples the viewing of 12,000+ real people 24/7/365. In terms of panel size relative to the overall population, OzTAM’s panel is among the world’s largest.
OzTAM uses a sophisticated metering system that captures viewing to all broadcast television channels on all TV sets in panel homes. OzTAM TV ratings, along with its BVOD measurement service for internet-delivered TV content, are key to Australia's new integrated Total TV database, Virtual Australia ('VOZ'), which brings together broadcast viewing on TV sets and connected devices to provide all-screen, cross platform planning and reporting for Australia's television industry.
