M is dedicated to only French songs like its local competitor in Île-de-France, Chante France.

In 1981, MFM was created in Lyon, then named as Radio Montmartre, and proposed a format essentially based on French chansons from the 1920s till the 1960s.

In 1995, it was authorized by the CSA to change its name to "Montmartre FM".

In April 2007, the programming was made around a musical format focused on relaxation and emotion, broadcasting mainly songs from the 1970s to today.

In June 2010, the station had been taken over by the Espace Group based in Lyon.
