[2] Fun Radio was created on October 2, 1985, in the south of France under the name FUN by Éric Péchadre, Pierre Lattès and Jean-Baptiste Blanchemain, who controlled six local NRJ franchise stations belonging to them (Nancy, Grenoble, Montpellier, Bordeaux, Carcassonne and Toulouse) and a Chic FM station (Nice) directed by Françoise Martin, director of antenna and programs with the company Cofirad SA.

The station started to focus around the current hits with a format of playing six songs in a row before every advert.

The appointment of Benoît Sillard to the station's director in 1989 allowed Fun Radio to find its own style.

In October 1992, to compete with the success of Bonsoir la Planète on Skyrock, Benoît Sillard launched the show Lovin'Fun animated by Le Doc, Christian Spitz, and Difool.

In the spring of 1994, Fun Radio broke its historical audience records with 8.7 points of hearing compared to 10 for NRJ, due to Lovin'Fun as well as the controversy around this show, with the French media regulator CSA having reminded the station following ethical questions and raw remarks.

In January 1995, breakfast host Cauet made a bad joke, comparing holiday clubs and German concentration camps, which later led to his dismissal by Fun Radio.

On November 3, 1997, Axel Duroux, then CEO of RTL2, took over the presidency of Fun Radio and placed Sam Zniber new antenna director.

In the fall of 1998, a new format appeared: the station changed its historic logo with a pink square which said "Fun" and follow by a blue oval said "radio", very similar to that of RTL and RTL2.

This new image attracted many criticisms from its listeners: the radio loses 1 audience point compared to last spring, until reaching historically low levels.

That year, M6 soled the 10% stake it owned to RTL Group (formerly CLT-UFA), which became a 100% shareholder of Fun Radio.

In 2004, Sébastien Cauet was announced on Fun Radio to animate the breakfast, which caused a media-legal conflict with the host Arthur who left the station.

In June 2005, the radio adopted a Pop Rhythmic format consisted of electronic-styled music and R&B hits.

Starting in September 2015, Fun Radio started an extension of Party Fun with a Before show for 2 separate hours (at 7 pm and midnight), which sandwiched 2 freeform programs: Lovin'Fun's slot of 8 pm-10pm, and a new Marion & Anne-So: Le Night Show from 10 pm-12 am to attract more female audiences.

Party Fun was wider revamped by allowing two different resident DJs to go in the mix weekly, one hour each, between midnight and 2 am.

A live overnight show and a 1-hour best-of Bruno dans la radio filled the remaining hours.

Current guest DJs include Mico C, Quentin Mosimann, Robbie Rivera, Mathieu Bouthier, Laurent Wolf, Dim Chris, Antoine Clamaran and David Vendetta.
