Abstract:
Switzerland is the first and, as of now, only country in which radio listening is not established by interviews but rather electronically. The Radiocontrol (RC) technique is based on audio comparison and has been delivering official radio data since January 2001. Previously 22,000 people were recruited by random quota sampling. Radiocontrol presents the radio world in a different light. Radio is far more than an accompaniment through the day. Media events such as the election of the Federal Council, for example, are reflected in the newly established data and show how listeners also use that medium selectively.
