He gradually created an empire in the cinema industry which lasted until 1972, with his creation of Artmédia, the first pan-European agency managing a combination of writers, directors and actors.
Clients included Bertrand de Labbey, Jean-Louis Livi and Serge Rousseau (who was to discover a new generation of French stars at the beginning of the 1970s, such as Patrick Dewaere, Coluche, Miou-Miou and Jacques Villeret).
Debord acquired a growing influence over the choice of publication of certain titles (Clausewitz, Baltasar Gracian, Jorge Manrique, poets of the Tang dynasty, Omar Kayyam, but also Jaime Semprún, Jean-Louis Moinet and others) while the marketing policy of the house broke with normal standards: there were no paperback editions of bestsellers, and no contact with the press.
Ten years later, Lebovici bought the Studio Cujas cinema in the Paris Latin Quarter and devoted it exclusively to showing Debord's films.
The unlimited friendship between the two men, apparently belied by all lack of similarity besides their respective age, provoked jealousy even among the close associates of Lebovici.
Pierre Guillaume approached Lebovici, in 1979, with a proposal to publish the Holocaust Denial text Le Mensonge d'Ulysse by Paul Rassinier.
