Recent protests have fuelled deliberations about the extent to which social media ignites popular uprisings. In this paper we use time-series data of Twitter, Facebook, and onsite protests to assess the Granger-causality between social media streams and onsite developments at the Indignados, Occupy, and Brazilian Vinegar protests. After applying a Gaussianization procedure to the data, we found that contentious communication on Twitter and Facebook forecasted onsite protest during the Indignados and Occupy protests, with bidirectional Granger-causality between online and onsite protest in the Occupy series. Conversely, the Vinegar demonstrations presented Granger-causality between Facebook and Twitter communication, and separately between protestors and injuries/arrests onsite. We conclude that the effective forecasting of protest activity likely varies across different instances of political unrest.

E-petitioning platforms are increasingly popular in Western democracies and considered by some lawmakers and scholars to enhance citizen participation in political decision-making. In addition to social media and other channels for informal political communication, online petitioning is regarded as both an instrument to afford citizens a more important role in the political process and allow them to express support for issues which they find relevant. Building on existing pre-internet systems, e-petitioning websites are increasingly implemented to make it easier and faster to set up and sign petitions. However, little attention has so far been given to the relationship between different styles of usage and the causes supported by different groups of users. The functional difference between signing paper-based petitions versus doing so online is especially notable with regard to users who sign large numbers of petitions. To characterize this relationship, we examine the intensity of user participation in the German Bundestag's online petitioning platform through the lens of platform data collected over a period of five years, and conduct an analysis of highly active users and their political preferences. We find that users who sign just a single petition favor different policy areas than those who sign many petitions on a variety of issues. We conclude our analysis with observations on the potential of behavioral data for assessing the dynamics of online participation, and suggest that quantity (the number of signed petitions) and quality (favored policy areas) need more systematic joint assessment.

This paper compares the volume of news articles per section in newspapers and social media platforms. To this end, two weeks of news articles were retrieved by querying the public Application Programming Interfaces (APIs) of The New York Times and The Guardian and the diffusion of each article on social media platforms Twitter, Facebook, Google , Delicious, Pinterest, and StumbleUpon, was tracked. The results show significant differences in the topics emphasized by newspaper editors and social media users. While users of social media platforms favor opinion pieces, along with national, local, and world news, in sharp contrast the decision of news editors emphasized sports and the economy, but also entertainment and celebrity news. Common to social networking sites is the prevalence of items about arts, technology, and opinion pieces. Niche social networks like StumbleUpon and Delicious presented a greater volume of articles about science and technology, while Pinterest is mostly dedicated to fashion, arts, lifestyle, and entertainment. Twitter is the only social network to have presented a statistically significant correlation with the distribution of news items per section by The Guardian and The New York Times. The results of this study provide a bridge between journalism and audience research and present evidence of the differences between readership in social and legacy media.

In this chapter I review the legacy of tabloid journalism in the context of digital media and discuss the transition from the strong editorial identity of tabloid newsprint to content curation that is both user-generated and created by paid staff members. Although the terms broadsheet and tabloid stem initially from paper size and format, I rely on this distinction to refer to editorial decisions that define newspapers' journalism standards, setting quality press (broadsheets) apart from popular newspapers (tabloids). I describe the heyday of tabloid journalism in the early twenty-first century, when newspapers shifted toward compact, visually appealing, and commuter-friendly editions featuring fewer stories with fewer words on each page and making space for the use of photography in storytelling. These structural changes to the process of newsmaking are reviewed in the context of the introduction of social networking technologies that once again disrupted newsmaking, with social media audiences behaving differently from the traditional readership of broadsheets and tabloids. I inquire whether entertainment-focused websites like Upworthy and BuzzFeed are positioned to displace the traditional tabloid media by churning out viral content that is mostly short, highly visual, sharable, and mostly accessed through mobile devices. In short, this chapter reviews the key assumptions underlying the opposition between broadsheet and tabloid in the context of digital journalism and offers a discussion on viral news websites and the personalization of news amplified by fragmented networked audiences. The article offers a contribution to the understanding of the world of tabloid journalism in the context of digital media.
