< Back Public Service Media and Platformization Pieter Van der Elst PhD Researcher This part of the SRP research project aims to develop in-depth knowledge on how an increasingly algorithmized media industry compels European Public Service Media (PSM) to alter their operational and value-related strategies. During a time period of 4 years, we will scrutinize how PSM’s part in the media value chain is affected and what that means for the company, the content and the end-user. A first phase of the research focuses on the organizational side of PSM. More specifically, we concentrate on the case of Flemish public broadcaster VRT and how they are operationalizing a digital and user-first approach in their digital audio strategy. Complementary analysis of the decision-making behind this organizational shift will be key to developing a thorough understanding of what it means for a public legacy media player to adapt to the ever-changing industry it operates in. In later stages of the project, our focus will shift towards what said transition implies for PSM on the levels of content production, distribution and the societal core values imbued. This part of the research will also broaden our scope geographically by including scrutiny of other European PSM organizations and how their methods compare to one another. Examinations of audience perspectives will conclude our research journey and provide us with indispensable insights on the topic. Through this research programme we aim to consolidate our understandings on algorithm-driven media operations and media-economics and media policy oriented PSM-research, not only serve the academic community, but also to provide small market PSM-organizations with tools to better understand and integrate algorithms, and assist policymakers in developing ways of regulating and measuring the impact of algorithms on media output and audience reach.

< Back Wrap-up of the RecSys Summer School 16 Jun 2023 Our key takeaways from the Recommender Systems Summer School in Copenhagen From 12 to 16 June, several researchers from the Media Economics & Policy Unit took part in the Recommender Systems Summer School in Copenhagen. During this Summer School, academics and industry leaders lectured on the practice, research, and state of the art in recommender systems. The lectures covered a broad range of topics from an algorithmic as well as a methodological perspective, including hands-on sessions. This week brought many interesting insights for our strategic research program on recommender systems and this short report highlights some of the key takeaways. Not an algorithm, but a system Recommender systems encompass more than just the algorithm itself. They require the thoughtful implementation of (a combination of several) algorithms that align with specific domain objectives, account for optimal user experience in different contexts, and seek to create mutual value for various stakeholders It is crucial to recognize that there is no one-size-fits-all approach to recommender systems. The strategy employed must be tailored to the specific domain in which the system operates, considering the unique objectives, economic factors, values and challenges inherent to that domain. For instance, in the realm of news, evaluating the system's quality necessitates considerations such as diversity and serendipity, speed and coverage. The recommender system design must consider the overall user experience. This involves understanding the various features and styles influencing users’ interaction with the platform, as well as analyzing the user journey and recognizing the impact of contextual dependencies on their preferences and needs. In both academic literature and practical applications, the primary goal of recommendation systems is to create value. This entails a reciprocal relationship between user values and business values. By addressing user needs and providing quality personalized recommendations that go beyond mere accuracy the system increases short-term engagement. Furthermore, these systems aim to cultivate long-term loyalty and build strong relationships with the target audience. In summary, well-designed recommendation systems enhance user engagement by offering personalized recommendations, optimizing the user experience, reducing information overload, fostering serendipitous discovery, continuously learning and improving, integrating social features, and thereby generate added value for business through increased user satisfaction, retention, and potential revenue growth. End of the artificial clean cut between content? Media mergers are changing the industry. One of the many examples is how RTL XL will become a part of Videoland. The question rises how the video-on demand platforms can blend different content types such as movies, series, TV programs, short clips and livestreams in an appealing way. An answer to that question could be answered by formulating the optimal user experience through recommender systems. Currently, the company is analyzing user behaviour in order to develop models that can be used in online user experiments. A next step will be to start A-B testing to create the optimal recommendation model. The goal of VOD platforms is to have loyal visitors, but it is a metric that moves very slowly. Currently, the recommendation system of the RTL is built up on three different types of recommendations: content-based, popular within the genre and collaborative filtering. Interesting fact: Personalized swimming lanes compared to editorials swimming lanes generate 30 min more viewing time per active user per month. The main goal of “this recommender optimizing project” is to work towards continuous loops. Sequential recommender systems are different in that sense that they convert user’s behavior trajectory into recommended items or services. It takes into account the current and recent preferences of a user for a more accurate recommendations. Implementing this new form of recommender system will be one of the key factors to generate a user interface with “blended content” that answers the customer’s needs. A critical stance in the evaluation of recommenders Being grounded in dominantly quantitative forms of assessment, recommender system evaluation needs to pay sufficient attention to real-world significance of numerical results and to whether outcomes actually make sense in applied cases. For instance, is an overall increase in prediction accuracy of a recommendation an accomplishment when large parts of the user base still receive bad recommendations and their preferences remain ill-defined? A call for qualitative sense-making of quantitative evaluation outcomes was certainly made at the Summer School. Also, research papers that seek to evaluate recommender systems often focus more on (incremental) increases in performance percentages than on a solid basis for their actual evaluation. In terms of relevance for the academic field, consequently, little contributions are made. Papers that are characterised by vagueness and technical complexity thus prevent real progress and cannot form the basis for further research. The lack of valuable longitudinal research in the domain of recommender systems can also be related to this. Lastly, by acknowledging that recommender systems impact not only the intended end-user and that their complex nature implies influences also on those not directly involved, we argue that multiple-stakeholder considerations should be the norm. We realize that the inherent complexity of recommender systems makes this a difficult endeavour. But in our attempts to evade the McNamara fallacy and to research in the most holistic way possible, the aim should always be to keep a multi-stakeholder involvement top-of-mind. Not solely in phases of design or evaluation, but as a constant reflective thought from the outset and throughout. Previous Next

< Back Rethinking Transparency in Public Service Media: a multidimensional framework for better governance Van den Bulck, H., Horowitz, M., & Raats, T. (2025). Rethinking Transparency in Public Service Media: a multidimensional framework for better governance. Frontiers in Communication , 10. https://doi.org/10.3389/fcomm.2025.1569363 Transparency has become a cornerstone of public service media (PSM) governance yet it remains inconsistently understood and applied. Increased scrutiny from various stakeholders has resulted in a need for actionable and meaningful transparency. Scholarly evidence highlights transparency’s benefits and risks, including potential misuse, as illustrated with current examples from Finnish PSM organization Yle and tVRT in Flanders (Belgium). This brief provides a multidimensional framework for actionable transparency efforts that allow PSM to move beyond ad hoc, reactive and partial approaches by elaborating key dimensions of transparency about what, when, how, by whom and to whom, transparency is required. Recommendations include fostering transparency practices that are meaningful and resistant to weaponization and politicization, developing participatory governance models, and leveraging transparency as a tool for organizational resilience.

< Back New publication: NORMalize Workshop (@ RecSys23) 15 Sept 2023 Exploring Power Dynamics in Digital Platform Markets: A Pragmatic Approach to Normative Recommender Systems We are excited to share that our research team has contributed a paper to the first workshop on Normative Design and Evaluation of Recommender Systems (NORMalize), co-located with the 17th ACM Conference on Recommender Systems in Singapore. Our paper, titled "Towards a Pragmatic Approach for studying Normative Recommender Systems: exploring Power Dynamics in Digital Platform Markets" examines two key economic dynamics prevalent in digital media markets that challenge the development of normative RSs. The first hurdle focuses on the susceptibility of digital platforms to lock-in and monopolization due to network effects, skewing the power balance towards system providers. The second hurdle delves into the "attention economy" and the engagement-centric logic in RS design. This logic, while successful in boosting engagement, might compete with explicit or long-term user objectives We illustrate the real-world significance of these dynamic with insights from the domains of video-on-demand and news media. Furthermore, by offering policy recommendations we wish to address the normative challenges that arise in RS design. PhD researcher Hanne Vandenbroucke will be presenting this paper during the NORMalize workshop on Tuesday, September 19. Previous Next

< Back Catching the waves: The case of VRT's digital-first audio strategy Van der Elst, P., Iordache, C., & Raats, T. (2025). Catching the waves: The case of VRT’s digital-first audio strategy. European Journal of Communication . https://doi.org/10.1177/02673231251370877 European public service media (PSM) are increasingly embracing strategies that balance digital platform tactics and meeting the public remit. This article addresses how a small market PSM is repositioning itself in a media landscape dominated by global platforms, streaming services and legacy media adopting platformisation strategies. We examine platformisation at the Flemish broadcaster VRT through the lens of its digital audio strategy. The study combines document analysis and expert interviews. Results show a strategic shift towards more focus on user needs and habits; a branding strategy revolving around the VRT parent brand; a necessary yet precarious presence on third-party platforms; a legacy-driven content offering complemented by online-only commissioning; and a firm editorial grip on content curation. VRT's take on these strategic innovations highlights a series of key dilemmas for PSM to reconcile public remit delivery and competitiveness in a platformised media landscape.

< Back Towards a Future-Proof Public Service Media? 1 Feb 2024 New report from the PSM-AP project Towards a Future-Proof Public Service Media? Lessons from a comparative analysis in seven media markets Tim Raats, Catalina Iordache imec-SMIT, Vrije Universiteit Brussel Catherine Johnson University of Leeds www.psm-ap.com Public service media (PSM) all over the world have consistently been subject to different forms of societal and technological transition. However, recent years have brought a number of new challenges. These include radical changes in media use, the advent of streaming services and the dominance of big tech. Moreover, the increasing diversity and polarisation of societies have led to the erosion of trust in traditional media. These have challenged the legitimacy of public service media as an institution and project, but have also affected the broadcasters themselves, requiring them to transform into fully digital, online-first organisations. In this context, we present results from the research conducted during the first year of PSM-AP, a large-scale comparative research project analysing ‘Public Service Media in the Age of Platforms’. In this brief, we provide an overview of the dimensions of platformisation, and a series of core findings and discussions on PSM and platformisation, based on the analysis of media laws, broadcast contracts and licences, annual reports, and current policy debates in the following markets: Belgium (Flanders and Wallonia), Canada, Denmark, Italy, Poland, and the UK.

< Back Welcome to the Metrics Jungle: Organizational Stakeholder Perspectives on Evaluation of News Recommender Systems in Industry Vandenbroucke, H., Michiels, L., & Smets, A. (2025). Welcome to the Metrics Jungle: Organizational Stakeholder Perspectives on evaluation of news recommender systems in industry. ACM Transactions on Recommender Systems, Highlights of RecSys ’24. https://doi.org/10.1145/3778173 News recommender systems (NRS) are increasingly implemented in news industry to enhance digital distribution, yet their development and evaluation are shaped by a complex interplay of organizational stakeholders with diverse objectives. This study investigates the real-world complexities of NRS implementation, considering the multitude of objectives on the NRS provider side by exploring how different stakeholder groups —from journalistic, commercial and tech logic— conceptualize NRS goals and assess their performance. Through 22 semi-structured expert interviews across four news organizations in Europe, we uncover a `jungle of metrics' where an overabundance of data insights does not necessarily lead to better decision-making. While traditional accuracy-based metrics like click-through rate (CTR) remain widely used, they fail to capture the broader strategic objectives that guide NRS adoption in industry. This paper identifies a critical gap between current academic evaluations of NRS and the business key performance indicators (KPIs) used in practice. Rather than evaluating NRS in isolation, stakeholders assess their contribution to overarching organizational goals, including reach, engagement, conversion, and retention. Our findings highlight the need for a more nuanced, multi-stakeholder approach to NRS evaluation that aligns with both business imperatives and journalistic values.

< Back People, personalisation, prominence: A framework for analysing the PSM shift to digital portals and interrogating universality across contexts Iordache, C. et al. (2024). People, personalisation, prominence: A framework for analysing the PSM shift to digital portals and interrogating universality across contexts. International Journal of Cultural Studies. https://doi.org/10.1177/13678779241296556 In the context of enhanced platformisation, Public Service Media (PSM) are once again forced to rethink the ways in which they achieve core public values. To this end, PSM have been prioritising the development of their own video-on-demand portals. To contribute to ongoing research, we propose a theoretical framework that can be applied by future PSM work, based on the operationalisation of platformisation in PSM policy documents and strategy. We identify the shared priorities across ten media organisations in seven media markets: Belgium—Flanders and Wallonia-Brussels, Canada, Denmark, Italy, Poland, and the UK. The study is based on the qualitative analysis of 61 documents, outlining the PSM remit and how they report and present themselves to governments, collaborators, and audiences, contextualised by ongoing national and regional debates. Findings confirm that the framework of people, personalisation, and prominence can serve as a useful theoretical basis for understanding and interrogating universality across contexts.

< Back The platformization of Public Service Media. A comparative analysis of five BVOD services in Western and Northern Europe Iordache, C., & Raats, T. (2023). The platformization of Public Service Media. A comparative analysis of five BVOD services in Western and Northern Europe. International Journal of Media and Cultural Politics , 19 (1), 3-22. https://doi.org/10.1386/macp_00070_1 Recent developments in the media industries have signalled the need for public service media (PSM) organizations to reposition themselves in order to reach audiences, and also secure financial sustainability and programming rights. In repositioning themselves, PSM have increasingly embraced some of the core characteristics of platforms by developing a central video-on-demand (VOD) service as portal to PSM services, investing in exclusive content and using data to create richer user experiences and gain insights into audience practices. However, this ‘platformization’ process comes with both challenges and opportunities to reach the public service remit. This article conducts an analysis of the on-demand portals of PSM, to uncover how platformization is reshaping the PSM core remit and values, and how these are transposed in online services and offerings. The research employs a comparative case study analysis of five VOD services of PSM in Western and Northern Europe: Belgium-Flanders (VRT.NU), BelgiumWallonia (RTBF Auvio), Finland (Yle Areena), Ireland (RTÉ Player) and Norway (NRK TV). The results discuss three main categories: interfaces and features, strategies for catalogue and content curation, and tools for discoverability and prominence.
