During its initial four years of broadcasting, the station faced financial struggles as well as internal conflicts, but managed to survive.

Mixshows (known as Club FG for most of the time) originally accounted for 30-50 percent of the entire broadcast week.

Today, the station broadcasts throughout the Parisian suburbs and in other major cities around France.

In September 2004 the radio started a free webradio service called Underground FG.

The station devotes 24 hours a day a mix of house, techno and dance music (similar to the original Radio FG), alongside older mixes that already aired on Radio FG.

In about February 2017, Radio FG decided to replace non-stop overnight music (Monday – Thursday mornings 2 am – 5 am) by non-stop rebroadcasts of interviews airing on the drivetime show "Happy Hour FG" with Antoine Baduel.

The reason for this change is still unknown, but it could be necessary to save money, especially because Mediametrie doesn't look a lot after the midnight-5 am slot.

carries a mostly-speech output from 8 pm to 6 am (Guillaume Radio 2.0, MiKL, Le PreMorning), and Fun Radio, another electronic station, plays far less music from 8 pm to midnight every weeknight (Lovin'Fun and Le Night Show).

In September 2018, FG expanded its DAB+ network beyond Marseille, Nice, and Lille, to include its radio stations in Béthune, Lens, Arras, and Douai.
