This book focuses on the notion of "vintage innovation" and its application in various old technology-based communities of practice. Some communities of practice resist and react to technological change by adopting new technological products ("vintage products") that extend the lifetime of their old, favored products and practices. There are a number of potential reasons for such strategic reactions, which are analyzed by the author. The book opens by reviewing the nature of technological change. Old technology-based communities of practice and their typical reactions to technological change are then discussed, and the concept of vintage innovation, introduced and explained. The book presents four case studies of communities of users in which vintage innovation emerged: analog photographers, radio amateurs, arcade videogame players, and disc jockeys.
