How do people consume news online? Here, we propose a novel way to answer this question using the browsing behavior of web users and the networks they form while navigating news content. In these networks, two news outlets are connected if they share a fraction of their audiences. We propose two crucial improvements to the methodology employed in previous research: a statistical test to filter out non-significant overlap between sites; and a thresholding approach to identify the core of the audience network. We explain why our approach is better than previous approaches using two data sets: one tracks digital news consumption during the 2016 Brexit referendum in the UK and the other during the 2016 Presidential Election in the US. We show that our filtering technique produces a completely different ranking of top sites uncovering structural properties in the audience network that would go unnoticed otherwise and consequently, providing a better measurement method to assess the level of fragmentation in the online news domain.

measures of audience overlap between news sources give us information on the diversity of people's media diets and the similarity of news outlets in terms of the audiences they share. This provides a way of addressing key questions like whether audiences are increasingly fragmented. In this paper, we use audience overlap estimates to build networks that we then analyze to extract the backbone -that is, the overlapping ties that are statistically significant. We argue that the analysis of this backbone structure offers metrics that can be used to compare news consumption patterns across countries, between groups, and over time. Our analytical approach offers a new way of understanding audience structures that can enable more comparative research and, thus, more empirically grounded theoretical understandings of audience behavior in an increasingly digital media environment.
The abundance of media options is a central feature of today’s information environment. Many accounts, often based on analysis of desktop-only news use, suggest that this increased choice leads to audience fragmentation, ideological segregation, and echo chambers with no cross-cutting exposure. Contrary to many of those claims, this paper uses observational multiplatform data capturing both desktop and mobile use to demonstrate that coexposure to diverse news is on the rise, and that ideological self-selection does not explain most of that coexposure. We show that mainstream media outlets offer the common ground where ideologically diverse audiences converge online, though our analysis also reveals that more than half of the US online population consumes no online news, underlining the risk of increased information inequality driven by self-selection along lines of interest. For this study, we use an unprecedented combination of observed data from the United States comprising a 5-y time window and involving tens of thousands of panelists. Our dataset traces news consumption across different devices and unveils important differences in news diets when multiplatform or desktop-only access is used. We discuss the implications of our findings for how we think about the current communication environment, exposure to news, and ongoing attempts to limit the effects of misinformation.
Whether people live in echo-chambers when they consume political information online has been the subject of much academic and public debate. This article contributes to this debate combining survey and web-tracking online data from Spain, a country known for its high political parallelism. We find that users spend more time in outlets of their political leanings but, generally, they engage in considerable cross-partisan media exposure, especially those in the left. In addition, we use a quasi experiment to test how major news events affect regular patterns of news consumption, and particularly, selective exposure. We find that the nature of news explains changes in users’ overall consumption behaviour, but this has less to do with the type of event than with the interest it arouses. More importantly, we find that users become more polarized along party lines as the level of news consumption and interest for news increases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
