As a journalist, in 1957 he joined the editorial staff of Radio-Luxembourg and participated in Armand Jammot's 10 Millions d'auditeurs, first radio magazine of the post-war period.
He was then sent to report in 1958 to follow the voyages of General de Gaulle to Africa, and went to countries affected by armed conflicts, civil wars or revolutions, notably in India, the Middle East, and Algeria.
[2] From these events, Courrière derived a monumental work that is still being referred to, a landmark in its proximity to the end of the conflict as well as the quality of the sources he obtained.
In 1967, he led the first edition of Les Dossiers de l'écran [fr] on the second channel of the ORTF, a program that will host other presenters during its 24 years of broadcasting.
In particular, he published novels and biographies of emblematic personalities from the first half of the twentieth century such as Joseph Kessel, Jacques Prévert, Roger Vailland or Pierre Lazareff.
