Owing to the proliferation of screens and networked culture, young fans have moved beyond being simply media consumers. Today they are content interpreters and creators—living in a remix culture, reconstructing transmedia narratives, and interacting with culture industries. Young fans' relationship to technology has transformed their discourses, interpersonal relationships, and the way they participate in communities. This book delves into these issues, looking at social and cultural approaches to human development to study the identities and activities of fan communities among young people. The book explores communities related to Harry Potter, One Direction, Fortnite, Warhammer, TikTok, and television programs. Drawing on an ethnographic approach and big data analysis, Adolescent Fans demonstrates how digital technology has changed not only fan behavior, but also research practices used to understand what it means to be a young fan.
