Moore and his publisher originally thought that the book would sell around 5,000 copies. By 2002, ten years after the first publication, more than 300,000 copies had been sold. Moore attributes this to word-of-mouth marketing, resonating initially with high-tech managers, then to engineers, venture capitalists and finally business schools.[5] The book's success led to a number of sequels including Inside the Tornado, Living on the Fault Line and The Chasm Companion.
