Radio prime time refers to the time slot when radio attracts the largest number of listeners. Unlike television prime time in the evening, radio prime time takes place in the morning, generally between 7 a.m. and 9 a.m., with a peak audience around 8 a.m. This time slot corresponds to a time when a significant portion of the audience is on the go, particularly while traveling. In December 2022, France Inter, as the leading station in this time slot, recorded an average of nearly 2 million listeners. According to Médiamétrie data, radio prime time attracts approximately 14 million listeners in France. Morning prime-time audiences are almost twice as high as those of the afternoon peak, which occurs between 4 p.m. and 6 p.m. In short, radio prime time represents a key period for radio stations, attracting a large and diverse audience, according to Médiamétrie data.
