Quelle « plateformisation » de l’information ? Collusion socioéconomique et dilution éditoriale entre les entreprises médiatiques et les infomédiaires de l’Internet

The production and distribution of news is currently characterized by both a switchover to the consumption of online information on mobile terminals, and a predilection for its circulation through social media. We propose a historical and theoretical analysis of this phenomenon of “platformization” as an accentuation of the infomediation process. Our analysis strives to reconcile the political economy of communication, media discourse analysis and technosemiotics of the Internet. Comparing empirical material from the past with some more recent indicators identified from interviews with industry players and an analysis of mobile news interfaces, we support the general hypothesis of an evolution towards more integrated and more asymmetrical relations between infomediaries and media companies that can be termed collution (socioeconomical collusion and editorial dilution).
