What is the least listened to FM radio station?

The least listened to FM radio station in the entire world would be difficult to specify. There are countless FM radio stations around the globe targeting unique audiences with varying levels of popularity. The popularity of a radio station depends on factors such as its broadcast range, programming preferences, listener demographics, and competition within the local market.

To accurately identify the least listened to FM radio station, specific listening data from all FM radio stations worldwide would be required, which is hard to comprehensively compile considering geographical disparities and the constant fluctuation of listenership. Radio listenership statistics are typically measured locally or regionally as opposed to compiling a single global chart.
