Radio listening duration in German-speaking Switzerland 2011-2023

¹ As of January 1, 2013, an expansion of the measurement methodology was implemented in the Mediapulse radio panel, which now allows the recording of radio usage with a delay of up to 60 seconds compared to the fastest distribution method. This means that the measurement was expanded to include the use of live web streaming (web radio). When interpreting the differences from previous years, this fact must be taken into account.

² At the beginning of 2018, some changes were made to radio research. The most important change is that a new generation of measuring devices (Mediawatch 4) is being used. (...) The changes in the methodology mean that the results from 2018 are not directly comparable with the results of previous years.
