A group of Japanese scientists have surprised themselves by being able to predict the success or failure of blockbuster movies at the box office using a set of mathematical models. The researchers used the effects of advertising and word-of-mouth communication to create a model that turned out to be successful in predicting how each movie fared once it hit the silver screen. The only data the researchers needed to put into the model were the daily advertisement costs of 25 movies that appeared in Japanese cinemas.
