How does the audience measurement process work?

Panel Selection

Households are recruited to OzTAM's panel via a large-scale Establishment Survey. The Establishment Survey defines the population to be represented and its characteristics.

The Establishment Survey is conducted to a high standard via telephone interviews throughout the year. In managing the recruitment process and monitoring turnover, the panel is an accurate representation of the population we provide data for.

Data Collection

Once a household has been recruited, all television sets are monitored by the meter system. The meter records and stores time, date, television set on/off, channel to which each television set is tuned, capturing all broadcast viewing. All residents and guests register their television usage using a remote control.

Data Delivery & Reporting

Every night the data is retrieved automatically via modem telephone software (silent phone call). The production system performs the collection, processing, validation, weighting and final production of each household's data.

Once the production processes have been completed, the television program information and ratings are integrated. All data undergoes rigorous quality control both electronically and manually. All results are released the following morning and the data is made available to our subscribers via a secure website.

What is the Gold Standard?

OzTAM's Gold Standard is a ratings analysis software benchmark that ensures consistency across the industry.

OzTAM supplies access to minute-by-minute ratings data. Subscribers to this data may choose the software system they wish to use for its analysis.

As a result, OzTAM has developed a Gold Standard, covering the arithmetical procedures for standardising the calculation of television audience measures.

Only Gold Standard accredited software can be used for analysing OzTAM data.

The OzTAM Gold Standard enables our clients to achieve consistent calculations of television ratings when analysing OzTAM data.
