My PhD thesis investigates political polarisation in the US and the fragmentation of society into diverse groups with a focus on how these phenomena reciprocally affect the production and reception of contemporary televised content. Although, at first glance, the new generation of streaming platforms and the multiplication of distribution media might suggest that Internet TV is expanding and perhaps even diversifying, a small number of companies are in fact producing a large majority of the content consumed while controlling the means of distribution via the Internet (Dixon, 2013). At the same time, streaming can also be seen as a haven for content on the margins, contributing to the creation of ‘niches.’ Due to a decline in the televised content that targets mass audiences, viewers are becoming more likely to cluster together with those who have similar viewing preferences. One can find safety within these communities, especially those whom society has marginalised. However, during this time of ‘cultural fragmentation,’ I question whether contemporary televised content is contributing to viewers increasingly ‘[existing] in a fragmented realm of niches and subcultures’ (Chayka, 2019) while also contributing to the phenomenon of political polarisation and to the fragmented nature of US society in general. My methodology for studying the series in my corpus is both qualitative and quantitative. The qualitative aspect includes microanalysis of the series featured in my corpus, interviews with viewers regarding their perception of these series, i.e., media consumption patterns, professed ideology, turnout behaviour, and investigations into how these series are being discussed by various news media and online over the spectrum of social media and message boards. The quantitative aspect includes the analysis of data released by streaming platforms, Nielsen NTI data (ratings, shares, demographics, social media interactions), Nielsen/NetRatings (unique visitors, demographics, page views, time spent info), and data acquired through Application Programming Interfaces such as CrowdTangle (for Facebook and Instagram) and the Twitter API. Entertainment media has now become one of the many areas of contestation currently affecting divided society in the US. While many studies have analysed the role played by news media in this contestation (Iyengar & Hahn 2009, Levendusky 2013, Benkler, Faris & Roberts 2018), my Phd thesis investigates the effects of serialised content in this issue.
