The Polish competition authority, UOKiK, has officially closed its investigation into the entities forming the Radio Research Committee (KBR). The investigation was initiated following market signals but ultimately found no evidence of competition law violations related to the methodology of the Radio Track study or the verification of its results.

UOKiK President Tomasz Chróstny stated that the companies within KBR jointly commission and finance the Radio Track study, which encompasses all radio stations operating under current licenses. The study is conducted by an external entity and provides audience measurement data for radio stations, which can be used for advertising pricing. Non-KBR members can purchase the Radio Track results to aid in their advertising strategies.

The investigation focused on whether KBR members might have violated competition law in shaping the Radio Track methodology and verifying its results. However, the thorough analysis conducted by UOKiK revealed no illegal actions. The Radio Track study is performed by the independent research institute Kantar Polska and adheres to industry standards. There was no evidence that KBR members interfered with the study's results or aimed to weaken the audience ratings of competing radio stations. Additionally, the investigation ruled out any blocking of other entities from joining the committee.
