This handbook provides a strong collection of communication- and psychology-based theories and models on media entertainment, which can be used as a knowledge resource for any academic and applied purpose. Its 41 chapters offer explanations of entertainment that audiences find in any kind of ‘old’ and ‘new’ media, from classic novels to VR video games, from fictional stories to mediated sports. As becomes clear in this handbook, the history of entertainment research teaches us not to forget that even if a field is converging to a seemingly dominant perspective, paradigm, and methodology, there are more views, alternative approaches, and different yet equally illuminative ways of thinking about the field. Young scholars may find here innovative ways to reconcile empirical-theoretical approaches to the experience of entertainment with such alternative views. And there are numerous entertainment-related phenomena in contemporary societies that still fit the „bread and circuses-“ perspective of the initial Frankfurt School thinking. So while the mission of the present handbook is to compile and advance current theories about media entertainment, scholars active or interested in the topic are invited to also consider the historic roots of the field and the great diversity it has featured over the past nearly 100 years. Many lessons can be learned from this history, and future innovations in entertainment theory may just as likely emerge from refining those approaches compiled in the present handbook as from building on neglected, forgotten, or marginalized streams of scholarship.
