Abstract:

After detailed testing, Radiocontrol has been the official measuring system for radio consumption in Switzerland since 1 January 2001. In the meantime two years have passed - time enough for the client radio stations to run their first analysis and adjust their programming.This paper demonstrates, utilizing several cases from public broadcasters as well as commercial stations, in what way and how quickly programming changes can be seen in the radio data. Since 1 January 2003 the data users also have an interest-typology at their hand which actually combines quantitative with more qualitative data.
