«Grok, is this true?»
Citizens increasingly reference AI tools in online political discussions, yet the communicative functions of these interactions remain underexplored. This study examines how Grok AI was mobilised by users on X ahead of the Portuguese legislative elections of May 2025. Using a grounded theory approach, we analysed 525 replies to posts of major political parties and leaders that mention (@) Grok AI. Most mentions were negatively framed, with only 1…
Jovens e as Notícias
Esta pesquisa analisa a predisposição dos jovens para aceder e participar em comunidades online na área do jornalismo tendo em conta as particularidades do consumo de média em 2025, marcado pelo evitar de notícias e o recurso popular às Redes Sociais Online (RSO) para aceder à informação. A investigação baseia-se num inquérito por questionário respondido por 174 jovens portugueses, com idades compreendidas entre os 18 e os 26 anos. Os resultados …
Scrolling with (dis)comfort on AI-generated news
Purpose. The increasing role of artificial intelligence (AI) in news production raises important questions about audience acceptance. This research explores group differences in comfort levels toward news generated by AI and news produced with AI assistance, focusing on the effect of the main news sources. It is hypothesized that using social media as a main gateway for news may influence comfort with AI-generated news due to the users’ familiari…
Building legitimacy
The study of public service media (PSM) has traditionally been examined within the context of mass communication. This article aims to advance the discussion by examining the legitimacy of PSM through the lens of citizens’ subjective representations. Using data from the Reuters Institute Digital News Report 2023 for Portugal, we explore how socio-demographic factors, news usage and trust influence societal importance attributed to PSM. Results in…
A taxonomy for Media Literacy in Portugal
Media literacy, which encompasses skills and knowledge considered essential for civic participation in social, political, and professional life, is an area that has been growing steadily. In Portugal, there is a wide range of entities that have developed media literacy initiatives, from public entities, universities, research centers, training centers, media organizations, among others. These actors are adopting different approaches and media lit…
Platforms as audio discovery ecosystems
Contemporary mediation gravitates around platforms, central structures where users and content converge. As the pivotal format for mediation through sound, intersecting culture, economy, technology and social processes, podcasting has drawn the attention of platforms which have been investing heavily on attracting/retaining producers and listeners alike, by facilitating production, securing the rights to exclusive content, and providing unique wa…
Da Personalização Algorítmica à Mediação Jornalística

Este estudo visa explorar as dinâmicas de consumo de notícias entre os jovens portugueses, com foco na personalização algorítmica. Utilizando dados do Digital News Report, investigamos como a preferência dos jovens por fontes algorítmicas de acesso a notícias digi…
Roles of journalists in media literacy initiatives
This paper aims to foster the debate on Media Literacy (ML) projects with a focus on disinformation. We analyse initiatives carried out locally in Portugal, considering the principles of ML, the necessary development of skills and competences, as well as the importance of the journalistic action and the consequences of platformization on professional practices. Mixed methods are applied to collect and analyse quali-quantitative data from ML proje…
Podcasting e pandemia. Da portabilidade e mobilidade ao confinamento e universos pessoais interconectados
A pandemia da Covid-19 trouxe consigo um conjunto de impactos e consequências, alguns dos quais de tipologia e dimensão ainda desconhecidas. O conjunto de práticas comunicacionais e de consumo de media não é excepção, tendo-se observado durante o confinamento de Março / Abril de 2020 uma alteração significativa dos padrões habitualmente atribuídos à sociedade portuguesa. O podcasting, enquanto formato intrinsecamente relacionado com aspectos como…
The role of journalism in combating fake news
This article reflects on the role of journalism in the deconstruction of fake news propaganda that came out in the media on the last day of the 2019 parliamentary election campaign in Portugal. We collected news items carried by the Portuguese media and contextualised this media coverage with regard to the impact of disinformation on confidence in the news with the help of data collated as part of the Digital News Report project. We found that jo…
Trust and fake news
In order to understand the role of contemporary journalism and the media system it is vital to consider consumers’ relationship with news content in terms of trust and perception of dubious content. This analysis is particularly relevant in a context where intense flows of information raise serious questions about individual ability to interpret, validate, and reproduce content. This analysis explores a news literacy scale used by Maskl et al. (2…
Publicidade Digital e Adblocking em Portugal – Apropriar ou Não Apropriar, eis a questão
The operative dynamics of the contemporary media sector are, in the digital age, increasingly susceptible to new tensions. On the part of financial structure and business models, few phenomena will be as relevant to investigate as the use of adblocking software, which has been increasing consistingly. This article addresses this issue in two ways: a) a theoretical review with a focus on the most recent and still scarce literature and b) to test t…
