This chapter outlines four key premises for digital journalism studies: 1) a massive shift in revenue streams because advertisers have largely migrated to the platform companies, and publishers developed subscription revenues; 2) an increased emphasis on audience metrics and analytics in the journalism sector; 3) shifting patterns of distribution in which platform companies non-proprietary to institutions of journalism have gained dominance; and 4) journalism has become more vulnerable to manipulation, disinformation, and a consequent lack of public trust. The chapter presents a meta-analysis of all articles published in Digital Journalism and argues that digital journalism studies is an interdisciplinary field, but with a strong footing in sociology and communication. The field focuses on journalism and digital media yet is marked by having to consider a form of separation (or dislocation) of news from journalism as a key transition and premise. The chapter also presents an outline of the book.
