The notion of a business model has recently emerged strongly in economics and management. One of the reasons for this is the development of the Internet, which has opened up new opportunities to build innovative offering formats and to ensure dematerialized, globalized and extended transactions. The development of information and communication technologies has also changed managerial and competitive strategies. They have helped to redefine how goods and services are made available and how they are produced, through their flexibility and modularity. These developments have stimulated the emergence of new forms of innovation in all sectors, particularly in the configuration of business models: diversified pricing forms, value-added service packages, new production and distribution methods, and new relationships with consumers. The chapter reviews the current state of business models and the various components that structure them. Far from representing only temporary phenomena of disruption, the dynamics at work suggest, on the contrary, permanent and omnipresent factors of change. The ever-changing redefinition of contents, offerings, consumption patterns and business models are now the structural element of the cultural economy.
