NRK P1 is a nationwide digital radio channel operated by the Norwegian Broadcasting Corporation (NRK). It is the result of the NRK radio channel reform initiated in 1993 by radio director Tor Fuglevik.
NRK P1 is the direct descendant of NRK's first radio station which began broadcasting in 1933. P1's programming is aimed at a broad mature demographic and it is Norway's most popular radio station, with approximately 1.9 million listeners daily.
P1's headquarters are located in the Tyholt area of Trondheim and most of its programmes are made there, except for news broadcasts which are produced, together with some other programming, at Broadcasting House in Marienlyst, Oslo.
With its 1176 FM transmitters using 124 different frequencies, NRK P1 was the largest radio network in Europe. However, all NRK's radio stations were gradually digitised during 2017 and are now transmitted via DAB+ and internet. NRK P1 also transmits in longwave at 153 kHz via the Ingøy radio transmitter (opened in 2000), which serves the country's fishing fleet in the Barents Sea.
