Inspired by a specific philosophy, the “free” movement first emerged in the software and academic research fields and has since enjoyed considerable economic success. In the field of culture, initiatives are born in a specific intellectual context, which we begin by briefly reviewing, and the revolutionary ambitions of pioneers have evolved with the development of Creative Commons licenses. These licenses, which originally were but one form of free license among many, have gradually gained a monopolistic position for numerous reasons, and in their 15 years of existence, their use has greatly increased. We present in this chapter an initial assessment of the use of these licenses based on the scattered statistical data that is available. This appraisal provides an overview in terms of the works available, the varied practices of creators and consumers of works, and the variety of economic models.
