    Why is it called ‘Virtual Australia’?

    OzTAM, Regional TAM and Nielsen have designed a database to represent the Australian population, a ‘Virtual Australia’.

    The Television Audience Measurement (TAM) Service uses a robust and large-scale Establishment Survey that collects data from 65,000+ interviews each year about respondents’ homes, TV viewing technologies and the demographics of their household members. In combination with Australian Bureau of Statistics official population data, the VOZ database is constructed to contain 26 million synthesised ‘individuals’ to represent the profile of all Australians.

    Why is VOZ needed?

    Australian TV viewing patterns are changing, thanks to the explosion in content, platform and device choice. The average Australian home now has 1.8 TV sets but 6.6 screens in total, and people are using all of them to watch television throughout the day – inside and outside the home. A small but growing number of people do not have access to a TV set, yet they stream broadcast content online. OzTAM, Regional TAM and Nielsen have built VOZ to capture the TV viewing that takes place on all screens.

    Is VOZ reporting available on an Overnight and Consolidated basis?

    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 7 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, though 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 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 however, VOZ is able to report on the same Consolidated 7 (i.e. ‘What Watched’) basis as the TV ratings service, to facilitate user analysis.
