摘要：The current news media context has consolidated social networks services as the new and decisive communication and interaction tools with users. In this regard, the purpose of this article is to analyze how the traditional audience participation has been affected by its implantation, focusing our inquiry on Facebook profile (being Facebook the network with the greatest audience in Spain and one of the most significant at the international level) of Cadena Ser news programmes: "A Vivir que son dos días", "Hora 25", "Hoy por Hoy" and "La Ventana". Taking as the starting-point the hypothesis that it is being underutilized and applying the content analysis, it has been studied the activity of these programmes in regard to their Facebook accounts. The outcomes certify how the station does not potentiate the interaction with listeners through their social networks services. The audience, however, it does employ these platforms to interact with each other. The arrival of this social media, therefore, favored and promoted dynamics of participation which, unlike traditional ones, are not driven or channeled through the radio medium but by the listeners themselves.
