Radio: The Medium with the Highest Reach in Switzerland

Radio is the medium with the widest reach in Switzerland. As Publica Data shows in the radio usage statistics published on Tuesday, this statement can be made for all three regional language markets. In the first half of 2009, 90.3 percent of the population aged 15 and over in German-speaking Switzerland listened to the radio for an average of 133 minutes per day. Both reach and use of the medium are slightly lower in the other language regions: 87.4 percent of people in Suisse Romande listened to the radio for around 121.5 minutes a day. In Svizzera Italiana, radio reached 88.3% of the population and was used for 122 minutes per day.
The SRG stations have the highest figures in terms of reach, duration of use and market share (see table below). Within the SRG, DRS1 is in first place, followed by DRS 3 in second place. Among the private radio stations, the highest reach was measured for Radio 24, followed by Energy Zürich in second place and Argovia in third.

Changes in methodology - direct comparisons with old data inadmissible
Three aspects have changed in the radio research system. The Radiocontrol sample had to be changed due to the new licensing areas for private radio stations. In addition, a period weighting was added to the daily weighting to improve accuracy and stability. Since the end of 2008, the Radiocontrol clocks have also been replaced by the successor model - the Mediawatch. The larger storage capacity allows more frequent measurements, which makes the measurements more accurate. Due to these changes, direct comparisons of the current semester data with older data are not permitted.
