In this paper we have evaluated the contribution that the BIDISO project and, more specifically, "Catalogo" y "Biblioteca Digital de Relaciones de Sucesos" database (CBDRS) have made in the field of Early Modern History Journalism in Seville.

The access to the records —and to the full texts through its digital reproductions— of hundreds of relations printed in Seville between the 16th and 18th centuries has allowed us to rewrite the history of the origins of journalism in the city, demonstrating the existence of marketing strategies leading to the consolidation of serialized formats and new layouts that can be named as journalistic, since the last years of the sixteenth century. On the other hand, the analysis of these Sevillian relations allows establish connections between the local and regional powers —noble families and colonies of foreign merchants— and their production, laying the first bases for an in-depth study of the structure of the market of the news in Early Modern Seville.
