In recent years, FM has been getting closer to its limits and in several regions of France, FM is saturated, meaning new radio stations cannot develop, and limiting the choice for listeners. In addition, many radio stations cannot be received in more remote locations. In response Arcom (the Regulatory Authority for Audiovisual and Digital Communication), issued licences for 25 national radio stations on the motorway axis of Paris-Lyon-Marseille, with the stations launched on 12 October 2021. Coordinating the entire radio ecosystem and informing listeners about DAB+ remain challenging, with progress too fast for some, and too slow for others.
