Every year around 24,000 interviews (disproportionate distribution according to federal states ) are carried out and summarized on a rolling basis for 12 months each. The CATI method (Computer Assisted Telephone Interview) is used. Sampling is based on the random last digit method .
Results of the survey:
- Market share
- Daily range
- Listening time
- Quarter-hour ranges
- Sociodemographic characteristics
The evaluation is carried out separately according to two target groups: on the one hand, the data of all Austrians aged 10 and over are published, on the other hand, the results are limited to the advertising-relevant core target group of 14 to 49 year olds.
Radio test affair (April 2016)
On April 19, 2016 it became known that the radio test numbers had been manipulated over a period of at least four years, from 2011 to 2015.
GfK admitted that this was a deviation of one to three percentage points. So far, the company has not wanted to comment on details such as the amount of damage, but corruption and oversight have been ruled out.
The ORF in particular would have benefited from the manipulation, in particular the Ö3 broadcasters and the ORF state radio stations. According to the media, the market research institute is now threatened with claims for damages. An independent company investigation was ordered.
On April 21, the managing director of GfK Austria, Alexander Zeh, announced his immediate resignation. The company denied any connection between the affair and Zeh's resignation. Zeh himself has not yet issued an opinion. GfK is now temporarily managed by the second managing director, Thomas Bachl.
The Association of Austrian Private Broadcasters is demanding compensation from GfK and ORF, they are talking about up to 20 million euros in lost advertising income.
