This chapter serves as an introduction to the issues examined throughout the book. After considering how key contextual factors such as culture, political economy, and technology combine to structure contemporary American journalism, the chapter offers a concise review of Twitter’s place in networked society as well as its significance for professional journalists and citizen media activists. This introduction also presents key guiding questions, provides a summary of the book’s central arguments, and offers a brief overview of the subsequent chapters.
