Why is it called ‘Virtual Australia’?

OzTAM, Regional TAM and Nielsen have designed a database to represent the entire Australian population, a ‘Virtual Australia’.
The Television Audience Measurement (TAM) service uses a robust and large-scale national Establishment Survey that collects data from 65,000+ interviews each year about respondents’ homes, TV viewing technologies in the home, and the demographics of their household members. The VOZ database is constructed to contain approximately 28 million synthesised (or virtual) ‘individuals’ to represent the profile of all Australians.

Why is VOZ important?

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 6.9 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.

How does VOZ work?

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 (broadcaster video on demand, or ‘BVOD’), together in a single, detailed database.

The VOZ database is constructed to contain approximately 28 million synthesised ‘individuals’ to represent the profile of all Australians using:
1. National Establishment Survey data (65,000+ respondents per year)
2. Actual viewing behaviour of 20,000+ individuals in OzTAM, Regional TAM and Rest of Australia panel homes
3. Information from streaming TV meters (STVMs) installed in ~6,000+ panel homes; and
4. Census level OzTAM VPM (Video Player Measurement) data on 16+ million connected devices monthly playing network content, granular to every viewing session.
