On 16th June 2017, P4 and Radio Norway shut down FM transmitters in Telemark, Buskerud, Hedmark and Oppland. Public broadcaster NRK had already closed down their transmitters in April 2017.
A week later, NRK shut down FM broadcast in the counties of Aust-Agder, Vest-Agder, Rogaland, Hordaland and Sogn og Fjordane.
P4 and Radio Norway will continue to broadcast on FM in Aust-Agder, Vest-Agder, Rogaland, Hordaland and Sogn og Fjordane until mid-September 2017.
The Norwegian Parliament decided previously that major cities will no longer have access to FM transmission, “for fear that they might take listeners from NRK and the other national channels,” according to radionytt.no
The vast majority of local stations in Norway do continue to transmit on FM; around 200 local radio stations have licenses to transmit on FM to until the end of 2017.
