What we do

As our mission states, our task is to define a common currency based on reliable, transparent, independent audience measurement system

What does this mean?

Nielsen TV Audience Measurement has been established to determine the viewing behaviour of the Australian metropolitan TV audience and thereby establish a 'rating' for each minute of broadcast time. This 'rating' becomes the currency that facilitates the purchase and sale of TV broadcast time.

How is this done?

In general terms, households are recruited to the metropolitan and regional panels via a large scale Establishment Survey that defines the population to be represented, and its characteristics. 

We install a ‘Peoplemeter’ to all working TV sets in the home which captures viewing to all broadcast television channels. A Peoplemeter is a little black box that records the electronic transmission signal being received by the TV. It then stores this information ready for automatic retrieval early the next morning.

Once the information is retrieved, it is collated and then distributed to TV Networks and other users on a daily basis.

9 Step Rating Process

Step 1: Establishment Survey
A large scale survey to define the population to be represented and its characteristics.

Step 2: The Panel
Homes are selected based on a statistical design ensuring the sample accurately reflects the markets being measured.

Step 3: The Peoplemeter
The Peoplemeter is installed on every working TV set in each panel home and collects 5 types of data: TV set time on/off, channel being watched as a digital audio signature, source of channel and who is watching.

Step 4: Polling
Each night between 02:00 and 0:600 the data stored in the panel home is retrieved via the meters’ transmission unit.

Step 6: Central Audio Matching
Audio signatures from people meters are matched to signatures from the reference site to identify household viewing from each TV set.

Step 7: Pollux, Production Software
Controls fundamental processes of collecting, consolidating and validating the daily household data into a minute-by-minute database.

Step 8: Program Name Database
Broadcast logs provided by FTA networks and EPG Logs from subscription TV channels are used to build a program database for integration with viewing data.

Step 9: Data Delivery
Each day data subscribers can download the previous day’s data to perform complex analyses using the various application software products available.
