摘要：This study is a reflection on the social and power relations that contextualize the scientific sources of the news, understood here as news promoters and potential digital influencers. The reflection on the ways in which these transformations are configured in journalism is developed based on a theoretical-bibliographic research, based on the questioning of the role of the sources of news in these processes. Two associated theoretical paths support the discussion of the work: on the one hand, the emergency of a journalistic ecosystem; on the other hand, the understanding of territoriality and temporality as articulated phenomena with an emphasis on changes in the circulation of journalistic information, both emerging conditions of contemporary societies.
