Research into current developments in newsrooms has paid a great deal of attention to convergence projects, focusing on emerging models of newswork and the attitudes of journalists towards change. This study proposes a longitudinal approach to the research of convergence, defined as a process where the outcomes are shaped by aspirations, power relationships and internal communications within a media corporation. The case of a European public broadcaster is evaluated through interviews performed over the span of five years. For the analysis of the discourses of journalists and managers, the article tries to build bridges between two traditions of innovation research: diffusion of innovations theory and actor-network theory. The proposed theoretical framework unveils the intricate and unpredictable nature of innovation processes in journalism. Results suggest that journalists' evaluation of the relative advantage of convergence depends on their position in the network. In the case analysed, the complexity of groups within the media company, the historical distance between newsrooms, and power relationships complicated the compatibility of convergence with the organizational structure.
