The industrial-age corporation is crumbling. The new form of wealth creation is the business web,and the new basis of wealth is digital capital. Schwab, eBay, Cisco, MP3, Linux, and dozens of other companies have transformed the rules of competition in their industries, seemingly overnight. They hijacked long-entrenched industry leaders with revolutionary offerings that surprised and delighted customers. These transformers could not and did not act alone: partners enabled them to move with stealth, speed, agility, and force. Such teams of innovators pioneered the business web, or "b-web" - the new platform for competition in the twenty-first century. B-webs - partner networks of producers, service providers, suppliers, infrastructure companies, and customers linked via digital channels - are destroying the firm as we have known it and generating wealth in entirely new ways. In "Digital Capital", information-age visionaries Don Tapscott, David Ticoll, and Alex Lowy describe and explain the b-web phenomenon and the forces behind its emergence. Drawing on three years of multimillion-dollar research into hundreds of b-webs as diverse as the Microsoft alliance and the automotive industry, the authors illuminate the five distinct types of b-web now in play: Agoras, Aggregations, Value Chains, Alliances, and Distributive Networks. Punctuating their analysis with a rich set of case studies, they provide the definitive guide to business model innovation in the digital economy.
