Description
Sweet (with his co-author and nephew David Wecker) details the creation of the Masters of the Universe toy line, its rise to immense popularity and then dizzying crash in which profits fell from a peak of $400 million in United States sales alone in 1986 to a mere $7 million in 1987. The book is primarily a view of the corporate side of creating Masters of the Universe, but details very little of the conceptual process behind inventing the individual Masters of the Universe characters and products.
