The term Experience Economy is first described in a book written in 1999 by B. Joseph Pine II and James H. Gilmore, titled "The Experience Economy". In it they describe the experience economy, as a next economy following the agrarian economy, the industrial economy and the most recent service economy. This concept has been previously researched by many other authors (see History of the Concept). Although the concept of the experience economy was born in the business field, it has crossed its frontiers to tourism, architecture, nursing, urban planners and other fields.
