One of the most authoritative books on high-tech marketing, a bestseller from the influential business publication Business Week, is devoted to the issues of marketing and sales of high-tech products in the mass market and related problems. In particular, the author argues that the early and mainstream market for high-tech products is divided by a chasm, towards overcoming which all the efforts of a high-tech enterprise should be directed. The existence of the gap is due to the significant differences between early market participants (tech enthusiasts and visionaries) and mass market participants (pragmatists). Tips on overcoming these differences, competent positioning and the right choice of market segments - all this can be found in the book by Geoffrey Moore. The book will be of interest to experienced and novice marketers, heads of companies developing high-tech products, students, as well as anyone whose work is related to marketing and advertising.
