Radio Paris evolved from the first private radio station in France, called Radiola, founded by pioneering French engineer Émile Girardeau in 1922. It became Radio Paris on March 29, 1924, and remained so through June 17, 1940, transitioning to state ownership in December 1933 as the premier station in the country. It kept its name from July 1940 until August 1944, but the station was then run by Nazis and French collaborators.
From 1940, collaborationist voices on Radio Paris included Jacques Doriot and Philippe Henriot. From 1942, Jean Hérold-Paquis broadcast daily news reports on Radio Paris, in which he regularly called for the "destruction" of the United Kingdom. His catch phrase was "England, like Carthage, shall be destroyed!", echoing Cato the Elder's slogan Carthago delenda est.
Its broadcasts were pitched directly against the BBC broadcasts of Radio Londres by Free French figures like Pierre Dac, who sang the taunting refrain, Radio Paris ment, Radio Paris ment, Radio Paris est allemand ("Radio Paris lies, Radio Paris lies, Radio Paris is German"), to the tune of La Cucaracha. On 8 May 1942 its transmitter in Bourges was blown up by the Resistance.
