Norway is first country to turn off FM radio and go digital-only

By Timothy Revell

Norway will be the first country to start turning off FM radio. Over the course of 2017, the FM radio network will slowly be switched off, with listeners only able to listen to digital programmes instead.

The northern county of Nordland will cease to broadcast FM radio from tomorrow, with other regions following suit throughout the year.
