This is a book on WOM (word-of-mouth) marketing studies.

It a well-known fact that everyone knew the Hollywood blockbuster Avatar would be a record-breaking film three days before its release. Successully solving this unprecedented challenge in marketing studies, authors Yoshida, Ishii, and Aragaki present a mathematical model of WOM (word-of-mouth) marketing success, which can be used to mathematize CGM (Consumer Generated Marketing). How to Make a Megahit explores the megahit production process and provides a concrete methodology for how to produce megahit products.

With Ishii’s thesis “Mathematical model for hit phenomena as stochastic process of interactions of human interactions” gaining significant attention from the academic and entertainment sectors abroad, a number of articles about his hit-prediction model have been written recently. This book offers an unprecedented challenge in marketing studies in providing a mathematical model of WOM (word-of-mouth) marketing success.
