A tale of two controversies: Situated AI frictions and the generative AI tsunami
What makes AI controversial? This article reports on an international expert consultation that we conducted between 2021 and 2023 to analyse recent controversies about AI in four countries: the United Kingdom, France, Germany, and Canada. Adopting a standpoint approach, this online consultation was designed to activate the collective intelligence of AI & Society expert communities to identify the most important but possibly overlooked controversi…
Governing sexism on TikTok: Ambiguities and tensions in community guidelines and corporate communication
While social media platforms increasingly present themselves as spaces for empowerment and diversity, they also reinforce gendered power relations through their governance practices. This study examines how TikTok’s U.S. community guidelines and newsroom articles between 2018 and 2022 address and govern sexism over time. Using a comparative approach, we analyze the relationship between platform governance and communication, drawing on Foucauldian…
Fixing election interference, safeguarding election integrity? Developments and dynamics of election-related policies on social media platforms
Platforms are key intermediaries of public and political communication, both heralded as facilitators of bottom-up democracy and condemned as democracy’s greatest danger. From misinformation to hate speech to election integrity concerns, the perils of platforms have become obvious in recent years, and platforms have increasingly developed rules and processes to handle problematic content. Elections are a catalyst for this development as both mome…
Studying the discursive order of artificial intelligence: Cross-national media coverage in China, Germany, and the US (2012–2024)
As a transformative force, artificial intelligence (AI) has become central to national interests, international prestige, and geopolitical strategy, sparking a global competition for leadership as countries vie for economic and political influence. This competition also unfolds discursively, as nations and sectors seek to shape the public debate about the economic, political, and societal implications of AI. Despite this, scholarship remains larg…
Who’s driving the AI hype in its formative phase? A longitudinal analysis of stakeholders in the US and German AI discourse on Twitter 2012–2021
AI has become an ambiguous yet powerful term that routinely refers to different technological advances, with stakeholders competing for public attention to influence public perceptions and decision-makers. Whilst research has focussed on specific AI stakeholders and identified industry dominance in debates around AI, a detailed investigation of the role of different AI stakeholders within public discourses in the formative phase of AI development…
Ai Industry Expectations and Underperforming Imaginaries
The panel takes up AoIR’s theme of how industry pre-mediates the future of internet technology and its effects and inquiries into alternatives. Utilising ideas from the study of sociotechnical imaginaries, it aims to locate, map, and critically examine AI imaginaries together with counter-imaginaries that engage with and intervene in those of the AI industry. First, it maps the discursive landscape of Big Tech ‘AI talk’ as a means to study ‘new m…
Strategising imaginaries: How corporate actors in China, Germany and the US shape AI governance
Corporate actors have been actively shaping the normative framing and socio-material infrastructure related to AI governance. We show how they achieve this by analysing documents from corporate actors headquartered in China, Germany and the US from 2017 to 2023, a pivotal period in the formation of public understanding of the topic. Drawing on conceptual work around ‘socio-technical imaginaries’ and corporate strategic behaviours, the analysis id…
Strong and weak AI narratives: An analytical framework
The current debate on artificial intelligence (AI) tends to associate AI imaginaries with the vision of a future technology capable of emulating or surpassing human intelligence. This article advocates for a more nuanced analysis of AI imaginaries, distinguishing “strong AI narratives,” i.e., narratives that envision futurable AI technologies that are virtually indistinguishable from humans, from "weak" AI narratives, i.e., narratives that discus…
On the controversiality of AI: The controversy is not the situation
Do public controversies about AI matter? Can they really make a difference to how AI is taken up or imposed on society? This introduction to the Special Issue on Analysing Articifial Intelligence Controversies (?) discusses how the contributing articles and commentaries address this question through original research and critical reflection. We argue that AI presents a watershed moment for the analysis of public controversies about science and te…
How Negative Media Coverage Impacts Platform Governance: Evidence from Facebook, Twitter, and YouTube
Social media companies wield considerable power over what people can say and do online, with consequences for freedom of expression and participation in digital culture. Yet we still know little about the factors that shape these companies' policy decisions. Drawing on data collected from mainstream English-language news sources between 2005-2021 and on a novel dataset of policy documents from the Platform Governance Archive (PGA), we investigate…
Sociotechnical imaginaries and public communication: Analytical framework and empirical illustration using the case of artificial intelligence
The concept of sociotechnical imaginaries (SIs) has been widely used and proven fruitful to understand diverging trajectories of technologies. While scholars have acknowledged the multi-layered materialisation of SIs and highlighted the importance of the communicative layer therein, this aspect has remained under-conceptualised. Therefore, we propose an analytical framework to better understand Sociotechnical Imaginaries in Public Communication (…
Mandate to overblock? Understanding the impact of the European Union's Article 17 on copyright content moderation on YouTube
This article presents the results of a study measuring possible overblocking due to copyright moderation and changes in the diversity of cultural products supply on YouTube in two European Union (EU) member states comparable in size and population, Germany and France. Both have adopted Article 17 of the EU Copyright in the Digital Single Market (CDSM) Directive (CDSMD) but Germany was 5 months ahead of France in changing its legislative regime fo…
Subnational AI policy: Shaping AI in a multi-level governance system
The promises and risks of Artificial Intelligence permeate current policy statements and have attracted much attention by AI governance research. However, most analyses focus exclusively on AI policy on the national and international level, overlooking existing federal governance structures. This is surprising because AI is connected to many policy areas, where the competences are already distributed between the national and subnational level, su…
Situating AI policy: Controversies covered and the normalisation of AI
Artificial intelligence has become an issue in public policy. Multiple documents issued by public sector actors link artificial intelligence to a wide range of issues, problems or goals and propose corresponding measures and interventions. While there has been substantial research on national and supranational artificial intelligence strategies and regulations, this article is interested in unpacking the processes and priorities of artificial int…
Policing Platforms: Addressing Power and Inequalities in Platform Policies
Social media platforms had for a long time successfully positioned themselves in the “sweet spot” between beneficial legislative protections and a remarkable absence of obligations (Gillespie 2010: 348), yielding little need to take direct responsibility for the content of users. Increasingly, and specifically since 2016, public and policy pressure has pushed platforms to become something different: not the allegedly neutral tech companies, but p…
We Learn Through Mistakes”: Perspectives of Social Media Creators on Copyright Moderation in the European Union
Artists promoting their cultural production on social media platforms must navigate an algorithmic environment that involves visibility, content distribution, and growing algorithmic copyright moderation. The latter was experienced by EU-based social media creators when Article 17 of the Copyright in the Digital Single Market Directive was enforced in the EU (Directive [EU] 2019/790, 2019). This research focuses on the understanding and experienc…
ChatGPT, LaMDA, and the Hype Around Communicative AI: The Automation of Communication as a Field of Research in Media and Communication Studies
The aim of this article is to more precisely define the field of research on the automation of communication, which is still only vaguely discernible. The central thesis argues that to be able to fully grasp the transformation of the media environment associated with the automation of communication, our view must be broadened from a preoccupation with direct interactions between humans and machines to societal communication. This more widely targ…

Der „Algorithmic turn“ in der Plattform-Governance: Die diskursive, politische und technische Positionierung von Algorithmen und KI als „technological fix“ für komplexe Herausforderungen
Die Regulierung von Plattformen ist zu einem zentralen Thema öffentlicher und politischer Debatten geworden: Wie sollen einerseits Anbieter von sozialen Medien mit problematischen Inhalten wie Misinformation und Hassreden umgehen? Und wie sollten wir andererseits Plattformen regulieren, z. B. indem sie für Inhalte haftbar gemacht werden oder zum Einsatz von Upload-Filtern gedrängt werden? Vor diesem Hintergrund rekonstruiert der Beitrag einen „al…
Talking AI into Being: The Narratives and Imaginaries of National AI Strategies and Their Performative Politics
How to integrate artificial intelligence (AI) technologies in the functioning and structures of our society has become a concern of contemporary politics and public debates. In this paper, we investigate national AI strategies as a peculiar form of co-shaping this development, a hybrid of policy and discourse that offers imaginaries, allocates resources, and sets rules. Conceptually, the paper is informed by sociotechnical imaginaries, the sociol…
Future imaginaries in the making and governing of digital technology: Multiple, contested, commodified
Visions of the future are omnipresent in current debates about the digital transformation. This introductory article and the full special issue are concerned with the function, power, and performativity of future visions and how they relate to the making and governing of digital technology. Revisiting existing concepts, we particularly discuss and advance the concept of sociotechnical imaginaries. In difference to ephemeral visions and partisan i…
"AI will fix this" - The Technical, Discursive, and Political Turn to AI in Governing Communication
Technologies of "artificial intelligence" (AI) and machine learning (ML) are increasingly presented as solutions to key problems of our societies. Companies are developing, investing in, and deploying machine learning applications at scale in order to filter and organize content, mediate transactions, and make sense of massive sets of data. At the same time, social and legal expectations are ambiguous, and the technical challenges are substantial…
Drug Markets and Anonymizing Technologies
Online drug markets taking advantage of social media and encryption software (e.g. Tor network) and cryptocurrencies (e.g. Bitcoin, Monero) to conceal the identity and physical location of their users are a relatively new area of internet research. Yet, a range of socio-technical innovations have contributed to the proliferation of drug markets on the Internet. Due to the illegality of drugs and drug dealing are anonymizing technologies regarded …

Between coordination and regulation: Finding the governance in Internet governance
Following recent theoretical contributions, this article suggests a new approach to finding the governance in Internet governance. Studies on Internet governance rely on contradictory notions of governance. The common understanding of governance as some form of deliberate steering or regulation clashes with equally common definitions of Internet governance as distributed modes of ordering. Drawing on controversies in the broader field of governan…
