It was established by Yacast France Institute in collaboration with Syndicat National de l'Édition Phonographique (SNEP) in response to the need of music label producers and publishing houses to test the commercial viability of certain dance releases.
It was initially broadcast September 2002 on Europe 2 on Saturday from 10 pm to 1 am[1] by Christophe Marceaux in two parts: a top 5 a general chart encompassing all styles (including R'n'B and electro), followed by a top 40 of Techno and House music.
Since September 2008, Club 40 chart has been broadcast on French NRJ radio station under the new title NRJ Club 40 mixed every Saturday evening by DJ Morgan Nagoya and presented by Romuald Boulanger.
Starting 2010, the chart is also being broadcast on French MTV Idol Saturday midnights until 1:30 am.
