NRK1

NRK1 (pronounced as "NRK en" or "- ein") is the Norwegian Broadcasting Corporation's (NRK) main television channel. Test broadcasts started on 12 January 1954, regular test broadcasts started on 13 April 1958 and regular broadcasts started on 20 August 1960. It is Norway's oldest and largest television channel and was the country's only free-to-air television channel until the launch of TV 2 in 1992. Previously known simply as "NRK", the channel is now known as "NRK1", to distinguish itself from sister channel "NRK2", which started broadcasting on 1 September 1996.
