In this special issue editorial, we introduce a research agenda for empirical app studies. First, we introduce the three main strands of scholarship that have engaged with (mobile) apps and infrastructures so far. This enables us to position the contributions to this special issue at the cutting edge of the research on apps and infrastructures. We present our theoretical perspective on the infrastructural situatedness of apps to foreground how apps are always relational and, therefore, situated in a technological as well as social and cultural sense. From this perspective, we outline the contours of the app/infrastructure stack, which proposes to account for the hierarchical layered structure of apps and infrastructures, including their various interrelations and interdependencies. Finally, we derive six emerging research themes for future app studies based on the eight contributions included in this special issue that we hope will motivate further innovative and critical research into apps and infrastructures specifically as well as into computational culture in general.

The purpose of this article is to operationalise an evolutionary perspective on the history of social media and to trace Facebook’s evolution from a social networking site to a “platform-as-infrastructure”. Social media platforms such as Facebook change constantly on the level of their platform architectures, interfaces, governance frameworks, and control mechanisms, all while responding to their larger environments. By examining the evolution of Facebook’s programmability and corporate partnerships, we develop an empirical historical analysis of the platform’s boundary dynamics that ultimately determine its operational scale and scope. Based on our analysis of a unique set of archived primary sources, we discern four main stages in Facebook’s long-term evolution and discuss the interplay between ongoing processes of “platformisation” and “infrastructuralisation”. We argue that these terms foreground complementary aspects of the platform’s efforts in balancing its expansion and adaptability to changing user needs and other “environmental dynamics” without risking its integrations and embedding in other domains, such as advertising, marketing, and publishing. Ultimately, our contribution illustrates how empirical platform histories can denaturalise the current dominant position of social media platforms, such as Facebook, revealing over a decade of incremental evolution rather than revolution.

This article discusses methodological approaches to app studies, focusing on their embeddedness and situatedness within multiple infrastructural settings. Our approach involves close attention to the multivalent affordances of apps as software packages, particularly their capacity to enter into diverse groupings and relations depending on different infrastructural situations. The changing situations they evoke and participate in, accordingly, make apps visible and accountable in a variety of unique ways. Therefore, engaging with and even staging these situations allows for political-economic, social, and cultural dynamics associated with apps and their infrastructures to be investigated through a style of research we describe as multi-situated app studies. This article offers an overview of four different entry points of enquiry that are exemplary of this multi-situated approach, focusing on app stores, app interfaces, app packages, and app connections. We conclude with nine propositions that develop out of these studies as prompts for further research.

Facebook's usage has reached a point that the platform's infrastructural ambitions are to be taken very seriously. To understand the company's evolution in the age of mobile media, we critically engage with the political economy of platformization. This article puts forward a conceptual framework and methodological apparatus to study Facebook's economic growth and expanding platform boundaries in the mobile ecosystem through an analysis of the Facebook Messenger app. Through financial and institutional analysis, we examine Messenger's business dimension and draw on platform studies and information systems research to survey its technical dimension. By retracing how Facebook, through Messenger, operationalizes platform power, this article attempts to bridge the gap between these various disciplines by demonstrating how platforms emerge and how their apps may evolve into platforms of their own, thereby gaining infrastructural properties. It is argued that Messenger functions as a 'platform instance' that facilitates transactions with a wide range of institutions within the boundaries of the app and far beyond.

Social media platform–industry partnerships are essential to understanding the politics and economics of social data circulating among platforms and third parties. Using Facebook as a case study, this paper develops a novel methodology for empirically surveying the historical dynamics of social media industry partnerships and partner programs. Facebook is particularly emblematic as one of the few dominant actors that functions both as data aggregator and as digital marketing platform whilst operating a multiplicity of dedicated partner programs that cater to a wide array of industry partners. We employ mixed methods by aligning digital historical research and interview methods: using “digital methods”, we reconstruct both ongoing and former declared platform–industry partnerships and programs with web data whilst conducting semi-structured interviews with selected platform partners to contextualize the empirical research. This enables us to address (i) the dynamic relations between social media platforms and industry partners, (ii) their diversification by catering to a growing number of stakeholders with distinct interests, and (iii) their gradual entrenchment as dominant actors within an emerging digital marketing ecosystem. By tracing how and when partnerships and industry alliances are forged, sustained, and terminated over time we are able to develop a critical account of the political economy of social data that addresses the politics of platforms and stakeholders as well as the consolidation of platform power.

The paper examines Facebook’s ambition to extend into the entire web by focusing on social buttons and developing a medium-specific platform critique. It contextualises the rise of buttons and counters as metrics for user engagement and links them to different web economies. Facebook’s Like buttons enable multiple data flows between various actors, contributing to a simultaneous de- and recentralisation of the web. They allow the instant transformation of user engagement into numbers on button counters, which can be traded, multiplied but also function as tracking devices. The increasing presence of buttons and associated social plugins on the web creates new forms of connectivity between websites, introducing an alternative fabric of the web. Contrary to Facebook’s claim to promote a more social experience of the web, this paper explores the implementation and technical infrastructure of such buttons to conceptualise them as part of a so-called ‘Like economy’.

This paper enquires into the politics of real-time in online media. It suggests that real-time cannot be accounted for as a universal temporal frame in which events happen, but explores the making of real-time from a device perspective focusing on the temporalities of platforms. Based on an empirical study exploring the pace at which various online media produce new content, we trace the different rhythms, patterns or tempos created by the interplay of devices, users’ web activities and issues. What emerges are distinct forms of ‘realtimeness’ which are not external from but specific to devices, organized through socio-technical arrangements and practices of use. Realtimeness thus unflattens more general accounts of the real-time web and research, and draws attention to the agencies built into specific platform temporalities and the political economies of making real-time.

This paper documents the results of an intensive "data sprint" method for undertaking data and algorithmic work using application programming interfaces (APIs), which took place during the Digital Method Initiative 2013 Winter School at the University of Amsterdam. During this data sprint, we developed a method to map the fields of Digital Humanities and Electronic Literature based on title recommendations from the largest online bookseller, Amazon, by retrieving similar purchased items from the Amazon API. A first step shows the overall Amazon recommendation network for Digital Humanities and allows us to detect clusters, aligned fields and bridging books. In a second step we looked into four country-specific Amazon stores (Amazon.com, Amazon.co.uk, Amazon.fr and Amazon.de) to investigate the specificities of the Digital Humanities in these four countries. The third step is a network of all books suggested for the Electronic Literature field in the four Amazon stores we searched, which offers a comparison to the field of Digital Humanities.

The blogosphere has played an instrumental role in the transition and the evolution of linking technologies and practices. This research traces and maps historical changes in the Dutch blogosphere and the interconnections between blogs, which — traditionally considered — turn a set of blogs into a blogosphere. This paper will discuss the definition of the blogosphere by asking who the actors are which make up the blogosphere through its interconnections. This research aims to repurpose the Wayback Machine so as to trace and map transitions in linking technologies and practices in the blogosphere over time by means of digital methods and custom software. We are then able to create yearly network visualizations of the historical Dutch blogosphere (1999–2009). This approach allows us to study the emergence and decline of blog platforms and social media platforms within the blogosphere and it also allows us to investigate local blog cultures.

This paper discusses methodological approaches to app studies, focussing on their embeddedness and situatedness within multiple infrastructural settings. Our approach arises by paying close attention to the multivalent affordances of apps as software packages, particularly their capacity to enter into diverse groupings and relations depending on different infrastructural situations. The changing situations they evoke and participate in, accordingly, makes apps visible and accountable in a variety of unique ways. Engaging with and even staging these situations, therefore, allows for political-economic, social and cultural dynamics associated with apps and their infrastructures can be investigated through a style of research we describe as multi-situated app studies. The piece offers an overview of four different entry points of enquiry that are exemplary of this overarching framework, focussing on app stores, app interfaces, app packages and app connections. We conclude with nine propositions that develop out of these studies as prompts for further research.

This short piece examines Data Selfie, an open-source Chrome browser extension that collects and analyses data about your behaviour on facebook.com. We describe how Data Selfie works, what data it does and does not collect, what kind of data profiles or "selfies" it generates, and what type of data awareness raising strategy it employs.

This project sets out to advance the study of mobile apps at the intersection with platform studies and explores what both fields of study may learn from each other. A novel empirical methodology is developed to explore the intricate relations between mobile apps and social media platforms. Our findings suggest to think of apps as relational software entities, simultaneously situated and distributed. Apps exist as part of wider ecologies made up of programmable infrastructures and controlled data flows.

The panel engages with conceptual and methodological challenges within a specific area of ‘internet rules’, namely the space of mobile apps. Whereas the web was set out to function as a ‘generative’ and open technology facilitating the production of unanticipated services and applications, the growing popularity of social media platforms, and mobile apps is characterised by proprietary services that facilitate accessibility but obstruct transparency, tinkering, adjustment, and repurposing. This broader development from ‘generative’ technologies to ‘tethered’ devices and services has been referred to as ‘appliancization’ by Jonathan Zittrain (2008). In addition to Zittrain’s focus on the proliferation of proprietary technologies, we suggest that platform infrastructures create specific conditions for the emergence of app ecologies and that apps and platforms are mutually dependent on a technological and economic level.

From this perspective, the panel explores a number of novel methodologies for app studies. So far, methodological approaches for studying apps have focused on end-user interfaces and how users interpret app affordances (McVeigh-Schultz and Baym 2015), qualitative analyses of their political economies and the politics of location (Dyer-Witheford 2014; Wilken and Bayliss 2015), their social norms of use (Humphreys 2007) or their affective capacities (Matviyenko et al. 2015). The empirical investigation of apps and their ecologies currently faces multiple challenges: First, in contrast to most data collected from web sites and platforms, user activities can neither be simply observed or scraped from front-end interfaces nor easily be collected via APIs. In order to access app data, researchers may need to participate in using the app, which only affords a partial view (e.g. in the case of Tinder, Snapchat, and messaging apps) thereby opening up a number of ethical concerns. Second, method development has to respond to apps’ fast update cultures. Like other internet-enabled technologies, apps are considered as services rather than products and have frequent development cycles, including design and features changes, which do not only require researchers to constantly adjust their tools and approaches, but which also make it particularly difficult to reconstruct the history of an app or its features.

This panel responds to these methodological challenges by advancing methodological approaches that all share a common device or medium-specific perspective, departing from the specific features of each app to attend to its data ecologies, political economies, practices, or histories, whilst reflecting critically on the relations between method and medium. One contribution advances digital methods for app analysis by mapping larger platform ecosystems in which apps emerge and thrive. It explores how apps reinforce, alter, and interfere in the interpretation of social media platforms and their features. Engaging with Facebook’s mobile app and its political economy, the second paper attends to the difficulties of getting access to historical app information whilst tracing relations between the introduction of new features and the advancement of the platform’s business model. A different approach to writing a microhistory of apps is offered in the third paper on the Twitter’s retweet button. Bringing together historical and ethnographic insights, this paper offers a detailed narrative of the becoming of a platform feature at the intersection of technicity, use practices, third-party apps and platform politics. The fourth and final paper focuses on the WeChat app and draws on ethnographic methods to explore the affordances of entanglement when the only way to study an app is by joining and participating in it.

All four papers approach apps not as discrete technologies, but as being situated and subject to distributed accomplishments of technicity, economics, practices, data, third parties, and platform politics. They connect platform studies and app studies by drawing attention to their intricate relations, e.g. in the case of platforms offering apps, apps built on top of platforms, apps facilitating practices that inform platforms, and apps functioning as platforms. The papers outline relations between and gaps in app and platform studies, as the study of platforms has identified the relevance of data circulation and the involvement of third parties, but has not explicitly asked how apps capitalise on platforms and vice-versa, or how they reinvent and inscribe into each other. From the perspective of app studies, adding a focus on platforms allows researchers to map the ecologies in which app data circulates as well as the regulatory rules and conditions for their development. The panel thus advances the field of app studies by exploring novel methods for empirical app research which allows to attend to the technicity, political economy, history, and enactment of app ecologies.

‘Super apps’ are on the rise. This study explores the characteristics, origins, and manifestations of these apps worldwide, presenting the concept of ‘super-appification’ to describe processes of conglomeration in the global digital economy. Super apps aim to become deeply integrated into people’s everyday lives, capturing and monetising essential activities. By analysing 41 super apps, we identify four distinct types of ‘super-app constellations’, showcasing different patterns and dynamics of conglomeration: ‘Swiss-Army Knife’ apps that consolidate services in one app, ‘Family’ apps that expand through subsidiaries, and ‘Host’ and ‘Hub’-style apps that leverage external developers. This typology offers a comprehensive understanding of the conglomeration patterns underpinning the rise of super apps, involving corporate, development and international expansion strategies. Ultimately, super-appification represents an intensified form of ‘appification’, as these apps increasingly pervade and commodify various aspects of everyday life, such as payment, insurance, grocery delivery, mobility and travel, with significant sociopolitical implications.

Critical scholars contend that ‘There is no AI without Big Tech’. This study delves into the substantial role played by major technology conglomerates, including Amazon, Microsoft, and Google (Alphabet), in the ‘industrialisation of artificial intelligence’ (AI). This concept encapsulates the shift of AI technologies from the research and development stage to practical, real-world applications across diverse industry sectors, resulting in new dependencies and associated investments. We employ the term ‘Big AI’ to encapsulate the structural convergence of AI and Big Tech, characterised by the profound interdependence of AI with the infrastructure, resources, and investments of these major technology companies. Using a ‘technographic’ approach, our study scrutinises the infrastructural support and investments of Big Tech in the AI sector, focusing on corporate partnerships, acquisitions, and financial investments. Additionally, we conduct a detailed examination of the complete spectrum of cloud platform products and services offered by Amazon, Microsoft, and Google. We demonstrate that AI is not merely an abstract idea but an actual technology stack encompassing infrastructure, models, applications, and an ecosystem of applications and companies relying on this stack. Significantly, these tech giants have seamlessly integrated all three components of the stack into their cloud offerings. Furthermore, they have developed industry-focused solutions and marketplaces aimed at attracting third-party developers and businesses, fostering the growth of a broader AI ecosystem. This analysis underscores the intricate interdependence between AI and cloud infrastructure, emphasising the industry-specific aspects of cloud AI.

Researchers, policymakers, and competition and regulation authorities worldwide recognize the utility of application programming interfaces (APIs) in powering the digital economy and driving datafication and platformization processes. However, it remains unclear how the APIs of leading social media relate to platform governance and how this relationship evolved. This article traces the evolution of Facebook’s APIs, which evolved from a relatively simple programming interface for data access into a complex layered and interconnected governance arrangement. The study draws on a large corpus of (archived) developer pages and API reference documentation to examine the history of Facebook’s API governance; that is, the governance of and by Facebook through its APIs. This historical analysis emphasizes the technical dimensions and dynamics of what, how, and whom powerful platforms seek to govern, thus highlighting the technicity of platform governance and how it evolved. Because APIs facilitate and govern the material conditions of app development and the social and economic processes they sustain, powerful platforms influence the evolution of their larger ecosystems. As such, the technicity of Facebook’s API governance represents a major source of the platform’s “infrastructural power.”

Social media platforms' digital advertising revenues depend considerably on partnerships. Business partnerships are endemic and essential to the business of platforms, yet their role remains relatively underexplored in the literature on platformisation and platform power. This article considers the significance of partnerships in the social media ecosystem to better understand how industry platforms, and the infrastructure they build, mediate and shape platform power and governance. We argue that partners contribute to 'platformisation' through their collective development of business-to-business platform infrastructures. Specifically, we examine how partners have integrated social media platforms with what we call the audience economy-an exceptionally complex global and interconnected marketplace of intermediaries involved in the creation, commodification, analysis, and circulation of data audiences for purposes including but not limited to digital advertising and marketing. We determined which relationships are involved, which are exclusive or shared, and identified key ecosystem partners. Further, we found that partners build and integrate extensive infrastructures for data-sourcing and media distribution, surfacing infrastructural and strategic sources and locations, or 'nodes', of power in this ecosystem. The empirical findings thus highlight the significance of partnerships and partner integrations and draw attention to the powerful industry players and intermediaries that remain largely invisible.

In this article, we propose a methodological outlook for historical platform studies to increase the prominence of platform historiography in the field and practice of web history and archiv-ing. We discuss the challenges of social media archiving and the research opportunities for 'platform' historiography by focusing on the distinctive characteristics of web-based social media 'platforms'. Based on our review of the literature, we argue that it is critical to foreground how contemporary platforms serve multiple user groups beyond end users (e.g. developers, business, investors) and how they operate on multiple levels (e.g. interface, architecture, ecosystem). By attending to the multiple sides and layers of social media beyond their end users only, we can reconstruct histories of platforms, not only as social networks, but also as technical artefacts , business organisations, and more. A focus on the materiality of platforms introduces numerous underutilised archived web sources that present significant entry points and research opportunities for platform historiography. We assess the availability of these archived sources across the leading web archives. Our results show that despite the challenges of social media archiving, platforms' resources are in fact well-preserved if we look beyond their end-user interfaces. Drawing on illustrative examples, we discuss two sets of entry points and materials for platform historiography at length: first, for writing developer-side histories, and second, for business-side histories. We conclude with recommendations for platform historians and archiv-ing practitioners and reflections on the future of platform historiography.

In this article, we empirically analyse the infrastructural relations between mobile apps and social media platforms and present a methodology to account for app–platform relations. Contrary to previous research on platforms and apps, we develop our approach from the perspective of apps based on a relational understanding of infrastructure. Our app-centric approach to platforms and infrastructure provides critical insights into (i) the kinds of third-party apps developed on the peripheries of social media platforms, (ii) the diverse practices and features supported and extended by those apps, and (iii) the messy and contingent nature of the relations between apps and social media platforms. Our approach provides insights into alternative forms of platform programmability beyond APIs and into social media-based ‘innovation’ app ecosystems driven by creative developer workarounds. Drawing on quantitative and qualitative forms of analysis of Android and iOS apps related to Facebook, Instagram, Snapchat, and Twitter, we explore how third-party apps engage with the specific ‘grammars of action’ of social media platforms and outline five distinct forms of regramming. With regramming, we refer to how app developers work with and around the affordances, action grammars, and constraints imposed by platforms for using their data and functionality. We conclude with conceptual and methodological reflections on the infrastructural relations between apps and social media platforms, app stores, and mobile platforms from the perspective of apps.

Facebook’s application programming interfaces (APIs) enable third-party app developers to access data and functionality and have become central to many of the platform’s ongoing data scandals and privacy concerns. Understanding how the platform and its APIs evolve and how it responds to issues requires looking closely and empirically at the evolution of access points, data structures, and graph data structures. The technicity of APIs is crucial for understanding the politics of data sharing and how APIs represent and structure phenomena and temporarily stabilise them. Instead of using APIs as an umbrella term for data retrieval, we conduct historical “technical fieldwork” for examining the evolving architecture and interfaces of Facebook’s web APIs. We contribute an in-depth technical and empirical perspective on the evolution of Facebook’s Graph API since 2006, and how it evolved into one of the most significant web APIs and an integral part of contemporary advertising infrastructures and web development cultures. Our empirical historical analysis of Facebook’s Graph API is based on the entire corpus of available archived developer documentation held by the Internet Archive. As we show, key changes in the Graph API evolution are characterized by phases of experimentation, standardization, commercialization, and regulation. We provide a “scalable reading” of the evolution of Facebook’s Graph API which provides insights in how data and data flows are governed through changes in data structures and permissions. By considering the evolving structures of APIs and individual data objects, we may develop further empirically informed critiques of platforms, APIs, and their data.

In this chapter, we discuss the research opportunities for historical studies of apps and platforms by focusing on their distinctive characteristics and material traces. We demonstrate the value and explore the utility and breadth of web archives and software repositories for building corpora of archived platform and app sources. Platforms and apps notoriously resist archiving due to their ephemerality and continuous updates. As a consequence, their histories are being overwritten with each update, rather than written and preserved. We present a method to assess the availability of archived web sources for social media platforms and apps across the leading web archives and app repositories. Additionally, we conduct a comparative source set availability analysis to establish how, and how well, various source sets are represented across web archives. Our preliminary results indicate that despite the challenges of social media and app archiving, many material traces of platforms and apps are in fact well preserved. We understand these contextual materials as important primary sources through which digital objects such as platforms and apps co-author their own ‘biographies’ with web archives and software repositories.

Data are neither inherently valuable, nor do all data have the same value. This contribution argues how data are made useful and valuable to specific actors and for specific purposes. It draws attention to the material politics of data flows and valuation, and to the many different actors and stakeholders who build the technological conduits and pipelines that facilitate the circulation and use of data. Therefore, it highlights the need to study the infrastructural layer of the global data market, as well as the central role of intermediaries who build and uphold these infrastructures for the exchange and use of data for different purposes. Both are important to situate the processes of datafication and data marketization in specific empirical settings.

Researchers, policymakers, and competition and regulation authorities worldwide recognise application programming interfaces (APIs) for powering the digital economy and driving processes of datafication and platformisation. However, it is unclear how APIs tie into the power of, and governance by, large digital platforms. This article traces the relationality between Facebook’s APIs, platform governance, and data strategy based on an empirical and evolutionary analysis. It examines a large corpus of (archived) developer pages and API reference documentation to determine the technicity of platform governance – the technical dimension and dynamics of how and what platforms like Facebook seek to govern. It traces how Facebook Platform evolved into a complex layered and interconnected governance arrangement, wherein technical API specifications serve to enforce (changes to) platform policy and (data) strategy. Finally, the article discusses the significance of this technicity in specifying the material conditions for app and business development ‘on top of’ platforms and for maintaining infrastructural and evolutive power over their ecosystems.
