VOZ provides national, de-duplicated audience and reach & frequency estimates of all-screen broadcast TV and BVOD viewing.
There are three types of duplication addressed in VOZ methodology:
- National view of market areas
- VOZ consolidates metropolitan and regional viewing into a national picture, accommodating viewing by people within areas that overlap between the metropolitan and regional markets. The people in overlap areas can contribute to two markets. This is sometimes referred to as ‘spill’ viewing.
- Service measurement duplication
- VOZ deploys a model to remove the duplication of viewing that can arise from bringing together two measurement services to a TV set i.e. TAM (broadcast TV) and VPM (BVOD).
- It is possible for current TAM measurement devices in TAM panel homes to pick-up BVOD streaming viewing on connected TV sets that corresponds to broadcast TV references. The same BVOD viewing is also being measured in VPM.
- VOZ introduces a modelled approach to identify and remove matched viewing sessions from broadcast TV audiences and preserve them in BVOD audiences – creating a de-duplicated measurement for Total TV dayparts and programs.
- Person level duplication
- VOZ supplies person-level exposure to broadcaster content (TV programs) and advertising across all screens (TV sets, computers, tablets and smartphones), allowing unique viewers to be counted. This means that people who have been exposed many times across multiple screens can be counted as just one viewer in VOZ Total TV reach measurement.
OzTAM is deploying Streaming TV Meter (STVM) technology into panel homes which will allow for the introduction of an enhanced technical solution to address service measurement duplication for future VOZ updates.

Determines the types of television audience measurement (TAM TV ratings) panel homes needed to reflect the overall Australian population and conducted via 65,000+ random mobile phone interviews annually. Questions include the number of working TVs in the home, presence of subscription TV services, who does the grocery shopping etc, in addition to age, gender, occupation category and household income. Every home in OzTAM, Regional TAM and Rest of Australia coverage areas has an equal chance of being contacted to participate in the national Establishment Survey.

An individual has been reached by an event (such as an advertisement, program, or time band) if they satisfy the minimum viewing criteria. The event’s reach corresponds to the total number of distinct individuals who meet this requirement.
The minimum viewing criteria for an event via broadcast TV is 60 sec of continuous viewing.

The VOZ Respondent Level Data (RLD) dataset provides the viewing information to content by individual people for the specific times they are viewing, for both broadcast TV and BVOD across all screens/devices. The RLD can be processed via Third Party Software Suppliers to calculate the audience of broadcast TV spots and BVOD impressions, as well as driving audience measurement for programs and dayparts. RLD is also referred to as Minute x Minute (MxM) or Elemental datasets in some industry tools and systems.

Spill viewing and overlap markets are two closely related but distinct concepts.
Unlike the distinct OzTAM and Regional TAM TV ratings service databases, which could only be analysed separately, VOZ now offers the opportunity to analyse metropolitan and regional markets together in a single, national Total TV database. This requires additional consideration on when to include or exclude spill viewing when analysing VOZ data.
Spill Viewing
Spill viewing is a Free-to-Air broadcast TV-only concept that relates to viewing of broadcast channels transmitted from a market that is outside of the market being analysed. Note in the TAM broadcast TV ratings service, program audiences are always to local market broadcast TV channels, and therefore no spill viewing is included.
Overlap Markets
Market areas are defined by the ACMA broadcast TV licence areas. Some of these licence areas overlap between metropolitan and regional markets, specifically:
- Sydney/Newcastle
- Melbourne/Gippsland
- Brisbane/Northern Rivers
- Brisbane/Maryborough
The viewing by people in these distinct overlap areas contributes to the market that the broadcast originates from as local market viewing. For example, people viewing broadcast TV channel Seven Sydney within the Sydney/Newcastle overlap area will have that viewing contribute to the Sydney market as local market viewing. Conversely, people viewing broadcast TV channel Seven Sydney within the Sydney/Newcastle overlap area will have their viewing contribute to the NNSW Market as spill viewing.
The following examples provide guidance for analysing viewing within VOZ:
- The viewing to a broadcast that originates from Sydney by a viewer in the regional Wollongong market is spill viewing (noting that Sydney and Wollongong do not overlap meaning this is unambiguously spill viewing).
- In the case where markets do overlap, such as when there is viewing to a broadcast that originates from NNSW Northern Rivers market by a person in the Brisbane markets:
- If that person is within Brisbane but not within the overlap area, then their viewing to the NNSW Northern Rivers market broadcast is spill viewing.
- If that person in Brisbane is specifically within the Brisbane/Northen Rivers overlap area, then their viewing to the NNSW Northern Rivers market broadcast is:
- Spill viewing if reporting the Brisbane market
- Local market viewing if reporting the NNSW aggregate market.
Importantly, the broadcast TV quarter hour files from the VOZ service excludes spill viewing.
Spill viewing and overlap markets are two closely related but distinct concepts.

Quantifies the total amount of time that an audience spends watching a particular television program, channel, or network over a specific period. It is calculated by summing the viewing of all individuals in the audience. For example, 100 viewers x 60 minutes = 6,000 total minutes viewed equally 60 viewers x 100 minutes = 6,000 minutes.
