FAQs

Various Gold Standard analysis, planning, trading and evaluation tools enable data subscribers to access VOZ data, including the VOZ reach & frequency (R&F) Portal & API and third-party software suppliers (TPSS). In addition, top line VOZ reports and insights are available via the VOZ website. Contact us at info@oztam.com.au for more information on subscribing to VOZ data.

As part of the construction of VOZ, OzTAM’s VPM census level data is enhanced via BVOD demographic modelling to deliver person-based estimates of viewing to live and video on-demand streaming broadcaster content. The available demographics in VOZ include the following standard age, gender and Grocery Shopper groups and are the building blocks to create any customised demographics.

Demographics no longer available with the change to VOZ include Total Households, Age-Groups of 16-24, 18-29, 25-44, 30-49, All Grocery Buyer (GB) related demographics and all Occupational Group related demographics. 

There will be, in most cases, demographics that closely align to any unavailable demographics in VOZ and it is suggested that you speak with your planning team to help guide alternative options. 

The removal of the GB demographics is in line with the introduction of Grocery Shopper (GS) demographics. This newer GS demographic was introduced to reflect the change in the grocery shopping role within the home as it includes the main grocery buyers as well as alternate grocery shoppers within the home.

VOZ will become Australia’s trading currency from December 29th 2024. This significant milestone enables trading on truly national, all-screen Total TV audiences for the first time. TV network annual rate negotiations for calendar year 2025, which start from the fourth quarter of 2024, will be based on VOZ Total TV data.

From December 29th 2024, the industry will move to accessing broadcast TV and BVOD data solely from the VOZ dataset.

VOZ delivers Overnight and Consolidated 7-day data reporting (traditional ‘What Watched’ reporting), although the VOZ database also provides the capability to deliver ‘When Watched’ reporting.

The TAM (OzTAM and Regional TAM TV ratings) databases are produced, and reporting is delivered, on a ‘What Watched’ basis. That means viewing, whenever it takes place during the seven days following original broadcast (such as time-shifted a few days later), is attributed back to the time that the program first went to air. In other words, viewing is consolidated to the broadcast TV event.

VOZ databases are produced on a ‘When Watched’ basis and offer both ‘What Watched’ and ‘When Watched’ reporting capabilities.

In ‘When Watched’ reporting, viewing is attributed to the time that the content was actually viewed. This is an important new perspective that VOZ offers on how broadcaster content is consumed over time, because a ‘When Watched’ database is able to show when that program was actually viewed, thereby revealing the ‘long tail’ of audience behaviour. Because the viewer determines the time at which they watch the content, BVOD viewing is, by definition, ‘When Watched’.

As VOZ is created as a ‘When Watched’ database, it is possible to accumulate up to 28 days (current operational parameters of the TAM service) of time-shifted viewing. However, the core service delivery for VOZ of Overnight and Consolidated-7 data aligns with the current commercial trading framework.

With respect to program rankings and audience thousands, VOZ is able to report on the same Consolidated-7 (i.e., ‘What Watched’) basis as the TV ratings service, to facilitate user analysis.

VOZ is delivered for the previous day at 11:30am based on preliminary program log information. Overnight data based on confirmed program log information (post-log) is released the following day, also at 11.30am (Saturday, Sunday, Monday data delivered on Tuesdays).

Consolidated-7 data is available 8 days after the research day. Consolidated-28 data is available 29 days after the research day.

VOZ data is available from the start of the 2022 research year (December 26th 2021).

User data that contributes to VOZ is fully anonymised. All OzTAM and Regional TAM TV audience measurement panel households opt-in with full consent. OzTAM and Regional TAM do not collect any information that can identify the person(s) that owns or uses individual devices. With respect to viewing on connected devices, users have given their consent to the broadcasters to use broadcasters’ websites and/or apps. The streaming TV meters only look for broadcast viewing activity and platform-level IP addresses for over-the-top and subscription video-on-demand (SVOD) services. VOZ, and the elements needed to deliver it, meet Australian privacy standards.

While VOZ is technically capable of reporting SVOD and other video providers, current specifications of the VOZ service covers television broadcast content only.
