Media are among the most influential institutions in modern societies. Media outlets – press, TV, Internet, radio, cinema – have become the leading players in the production and diffusion of information. Universal access to information, knowledge and pluralism of opinions are fundamental vectors for promoting a democratic and free society. However, the production of information is costly and the survival of media outlets crucially depends on the possibility of financing their activities. To avoid overloading consumers with all the costs of information production and promote as much as possible a universal access to information, media outlets have long relied on the combination of circulation/subscription revenues and advertising revenues (sometimes complemented by public subsidies) to finance their activities. The conventional business model used by media firms exploits their role as platforms of interaction between two categories of users: audiences (consumers) and advertisers. Exchanges arising in media markets often generate cross network externalities (between advertisers and consumers, and vice versa), producing interactions between the demand for advertising and the demand for media content. Accordingly, traditional media outlets naturally appear as two-sided platforms. In light of all changes carried by the digital disruption and the convergence phenomenon, the frontiers of media markets are going through a process of deep transformation. The cost of information provision and diffusion has become much lower and the speed of information exchange has enormously increased. This process has immensely expanded the possibilities to create value.
