This second edition explores the relationship between politics and media, with a particular emphasis on the significant disruptive changes to media and technology that have faced journalists, campaigners, and the public in recent years. The first edition, in 2014, described the earliest elements of social and online media: Web 2.0, the 'information economy,' and the changes from traditional broadcast media to the early online world. With the rise of TikTok, the 'fake news' claims of Donald Trump, the decline of local news, and the anti-democratic impulses that drove the January 6, 2021 coup attempts, the last decade has provided a rich and sometimes confounding set of disruptions to political communication that deserve attention. Technology has disrupted political communication in the online environment exceptionally quickly over the last decade, and this book provides a framework for understanding the intersections of these disruptions and their effect on an already-fragile democratic circumstance in the United States.
