This document summarizes research conducted by the Danish Broadcasting Corporation using an undercover agent method to gain new insights into how people listen to the radio news. Agents monitored their spouses or colleagues' radio listening behaviors without their knowledge and then participated in interviews about what was observed. The research found discrepancies between perceived and actual radio news listening habits and identified specific issues causing dips in listening. Changes implemented based on these findings initially reduced listening dips by 50% though their effectiveness decreased over time, highlighting the importance of monitoring solutions as well as identifying problems.
