We encounter media everywhere: Design determines whether we perceive objects and how we judge them and it corresponds in many ways with their content. This book provides a comprehensive introduction to the world of media. The chosen perspective is holistic and sociological, historical and psychological aspects are touched upon where appropriate, and practical exercises complete the book. This book is based on the book "Einführung ins Mediendesign" by Maja Tabea Jerrentrup written in German. The DeepL-based translation has been fully proof-read and the edition has been updated, revised, and extended.
