L’influence de la structure de marché sur la diversité éditoriale et les formes de mobilisation de la main-d’œuvre dans la presse magazine.

The concentration in the media has been very strong over the last two decades, particularly in the magazines. This article aims to analyze the influence of this market structure on diversity of production in the press on one hand; and on the types of labour force employed (titular or pigistes) on the other. Based on several interviews and surveys conducted among French journalists, we conclude that the influence of the pige system on the diversity of titles is ambiguous.
