M40 le klub' is the late-night club and electronic channel of M40, an independent French internet radio network running well over a hundred themed streams, with le klub' handling the dance-heavy overnight slot. The name attached to that network carries more French radio history than most listeners realize, because it once belonged to a station regulators effectively forced out of existence.
The station that tripled its audience playing music nobody else would
Before there was an M40, there was Maxximum. Launched as Aventure FM in 1987 and acquired by CLT, the Luxembourg broadcaster behind RTL, the station rebranded as Maxximum on October 23, 1989 under director Eric Hauville, built around dance and house music that was otherwise unavailable on French airwaves, according to a history compiled by franck.org. The bet worked immediately. Parisian audiences tripled within three months, and by October 1990 the station held roughly 1% of the national market, a real foothold against entrenched youth stations like NRJ, Skyrock, and Fun Radio.
Killed by a merger it did not choose
Regulation, not ratings, ended Maxximum's run. France's broadcasting authority, the CSA, stripped the station of its Rhône-Alpes frequencies in December 1990, and anti-concentration rules barring CLT from owning multiple national networks forced Maxximum into a merger with Metropolys, a rival station built by André Hibon and Antoine Gabert. At midnight on January 6, 1992, Maxximum went off the air for good, replaced instantly by M40. The new station cut its dance programming and pushed French-language music up to 30% of rotation from 7%, a change that alienated the audience Maxximum had built. Without the ratings to justify itself, M40 was renamed RTL1 in January 1995 and RTL2 a few months after that, closing out the name's first life after barely three years.
The name's second life, now purely online
The M40 running today is a different operation, an independent pure-player network streaming more than a hundred genre and decade-specific channels with no terrestrial FM signal at all. Le klub' occupies the network's overnight slot, running club and dance-oriented programming from 10pm to 6am among stations spanning decades from the 70s through the 2020s, according to the network's own channel listings. Whatever the exact relationship between this M40 and the one regulators dismantled in 1992, the overnight dance format now running under that name is closer to what the original Maxximum was built to do than anything the merger that first killed the M40 name ever was.
