FAQs

1. VOZ brings broadcast TV ratings estimates, derived from 20,000+ viewers in OzTAM, Regional TAM and Rest of Australia panel homes, and 16+ million devices streaming TV content (broadcast video on demand, or ‘BVOD’) monthly, together in a single, detailed database.
2. The VOZ database is constructed to contain approximately 28 million synthesised ‘individuals’ to represent the profile of all Australians using:
   • National TAM Establishment Survey data (65,000+ surveys per year);
   • Gold Standard TV ratings calculations based on the actual viewing behaviour of 20,000+ individuals in OzTAM, Regional TAM and Rest of Australia panel homes;
   • Information from streaming TV meters (STVMs) installed in ~6,000 panel homes; and,
   • Census level OzTAM VPM (Video Player Measurement) data on 16+ million connected devices monthly, playing network content, granular to every viewing session.

Foxtel decided to leave OzTAM’s primary measurement system and the Australian television currency in favour of exploring an alternative measurement approach. As a result, from December 15, 2024, viewing to Foxtel, Foxtel Now, Kayo Sports and all subscription TV channels on the Foxtel platform, is no longer reported in the VOZ Total TV currency. Foxtel viewing is included in the VOZ dataset for research years 2022, 2023 and up to and including December 14, 2024.

VOZ provides full national coverage which includes free-to-air broadcast content viewed in metropolitan and regional TV markets (including overlap areas) as well as the ‘Rest of Australia’ aggregate market. Rest of Australia refers to all other regions of Australia outside of the existing OzTAM and Regional TAM markets, including the combined TV markets of Darwin, Remote Central + Mt Isa, Griffith, Mildura, Spencer Gulf (Port Pirie/Broken Hill) and Riverland/Mt Gambier.
