In this doctoral thesis, we propose ourselves to work with the changes of Audiovisual Journalism which were intensified by the internet and new digital technologies phenom, most of all, the relations between usage of modes of production, distribution and audience all over the world. In this scenario, we recognize that the TV journalist needed to amplify his mainstream knowledge to multiple screens on social media, using the broadcast model and approaching Audiovisual Journalism language with web environment. Therefore, and sustained by the transorganizational, the transnational and the interpretive community theory, we investigated the TV productive routines of seven TV broadcasts from Portugal (RTP, primarily, and TVI, SIC, CMTV, Banda TV, Globo and Record), acknowledging that journalism activity is linked to a social-historical-cultural identity recognized and comprehended by its productive subjects and is always changing. So, we launched the Transterritorial Interpretive Community concept, articulating the brazilian journalism experience and the portuguese journalism production. In order to do this, the methodological tooling uses hues composed of Audiovisual Materiality Analysis (AMA), participant observation, autoethnography, and semi-structured interviews – total of 37, with 15 hours, 10 minutes and 4 seconds recorded. From that consolidated methods, we also propose our own methodology to analyze the productions flow between multiplied screens, named beting methodology, with the intention of mark the breakups, continuities and potentialities between TV journals and webscreens in Portugal.
