A concert tour that grossed more than two billion dollars, fans buying many copies of one album for the photo cards inside, shareholders who treat a chief executive as a hero, and designer toys reselling for several times their price within hours of a drop all run on the same engine: emotional attachment turned into spending, labor, and market power. Across ten modules and 40 sessions, this collection explains that engine as an economic system. It starts with the economics of attachment, examines the K-pop and J-pop idol industries as the most fully engineered form of fandom, then follows the model into Western superstars, founder and product fandom in technology, retail investing and tokens, and the wider world of sports, anime, creators, and collectibles. Every case is read through the same questions: how value is created, who captures it, and what it costs whom. The aim is a reader who can explain how fan businesses make money, why some fandoms are so valuable, and how to tell a healthy fan relationship from an extractive one.
