Below you can find survey results from 1992 onwards. 1992 was the first year the survey was carried out in full. Results show radio listening the average day, based on data for a full year:
- market shares - share of total listening time
- daily reach - listeners as share of population
- listening time - average time spent
Market shares the average day, distributed by all
In 2006 the number of interviews was reduced from 60 000 to 30 000. At the same time the age limit was changed from 9 years plus till 12 years plus.
Average listening time in the survey is much higher than in the new electronic PPM-panel - probably due to the method used to distribute minutes of listening time between channels. Listening is measured and distributed in blocks of 5 min. and 15 min.. The resulting total is higher than the actual listening time per channel put together, and far higher than the results of the new electronic PPM-survey, which now is being used as the radio channels' official ratings. An other reason for the difference might be be that interview data are memory based and less accurate than electronically recorded data.
P3 and P4 were launched in september 1993. As results are averages based on data collected the whole calendar year, results for 1993 will be lower than the actual data for the period September - December.
