OzTAM’s foundational measurement assets
Our world-class all-screen measurement services are built on proven, robust inputs that ensure data accuracy and rigor. We uniquely combine minute-by-minute actual broadcast TV viewing data with census-level online streaming viewing, validated by a robust, representative person-level panel.
Television Audience Measurement (TAM) service
OzTAM’s TAM service measures actual viewing behaviour from 5,250 metropolitan alongside Regional TAM’s 3,200 regional panel homes including Rest of Australia to deliver actual viewing of approximately 20,000 viewers 24 hours a day, 365 days a year.
Panel Recruitment
Households are recruited via the Establishment Survey, with more than 65,000 interviews conducted annually to ensure the panel accurately represents the Australian population.
People Meters
Sophisticated people meter technology uses audio content matching to identify free-to-air broadcast channels, whether viewed live or time-shifted, by comparing panel home audio to a comprehensive reference library.
Streaming Measurement
Streaming TV Meters, installed in ~6,000 panel households, measure all streaming video consumption (including SVOD) across connected devices within the home.
Currency Integration
TAM data, independently collected by Nielsen TAM on OzTAM’s behalf, is a key input into the VOZ Total TV currency dataset.
Video Player Measurement (VPM) service
OzTAM’s VPM service measures free-to-air broadcasters’ BVOD content streamed live and on-demand across 16+ million connected devices each month. VPM uses SDK integrations within broadcaster players, combined with Streaming TV meters in the broadcast TV panel, to collect minute-by-minute census-level viewing data. This is enhanced through demographic modelling to deliver person-based insights, including co-viewing on connected TVs, using inputs such as panel-based measurement across programs, genres and devices over time, first-party registration data and VPM census-level device data.
VPM’s granular dataset is a key input into the VOZ Total TV currency, enabling a unified and accurate view of Total TV viewing across devices, audiences and platforms.
Establishment Survey
Conducted on behalf of OzTAM and Regional TAM, the Establishment Survey (ES) defines the population to be represented and its characteristics. The ES provides intelligence on households, people, and in-home technologies (including working TVs). Every private household across OzTAM, Regional TAM and Rest of Australia coverage areas has an equal chance of selection. Panel homes are recruited from respondents to ensure statistically robust representation across age, gender and occupation groups.
The VOZ synthetic population models the entire Australian population using anonymised Establishment Survey data, to which broadcast TV and BVOD viewing is attributed, forming the VOZ Total TV database.
