In a world increasingly shaped by digital technologies and personalised information feeds, this leading textbook supplies the theoretical tools and knowledge to understand how media influence individuals and society. With an interdisciplinary approach, Ott and Mack explore media's role as a powerful socializing force, addressing the key areas of media technologies, industries, messages, and audiences. Each section delves into distinct critical perspectives, such as Marxist, feminist, and queer analysis, alongside exclusive chapters on pragmatic and erotic approaches. The fourth edition includes significant updates, including a detailed examination of the ecological impact of digital media and unique engagement with Byung-Chul Han's philosophy. Throughout, revised chapters incorporate contemporary examples, cutting-edge pedagogical features, timely discussion of global trends, and much more.
