(FILES) French actress Catherine Deneuve, French journalist Michel Denisot and French singer Serge Gainsbourg attend the first anniversary party of private television channel Canal Plus at the Palais Omnisport of Bercy in Paris on November 4, 1985. Impertinent, provocative, subversive: Canal+, born in 1984, imposed a tone that quickly became its trademark. In the Bollore era, all that remains is "Groland" on the encrypted channel and a few torchbearers elsewhere. On November 4, 2024, Canal+ will be celebrating its 40th anniversary.
