Despite the Internet's phenomenal impact on business and its reach across all sectors, no model has emerged for thoughtfully valuing companies' Internet efforts. In addition, strategies for effectively competing in this environment are just beginning to materialize. This book addresses both of these critical aspects of the Internet and offers business models and strategies for better understanding this important phenomenon. In the words of the authors, 'The framework (presented here) allows users of the text to make more informed theory-based arguments as to how successful an Internet-based firm is likely to be, how much it might be worth, and the relative merits of formulating and implementing an Internet strategy for an established firm.' A guide to show how to value Internet efforts and create a business model, with 14 case studies from such companies as Microsoft, Netscape and HotMail.
