Shift in technological paradigm usually brings critical impacts to existing products, companies and societies. Although the Schumpeterian economists have well discussed the destructive impact of technological change of this type, systematic analysis of paradigmatic change in technology surely help technology managers in allocating research resources. This study develops an analytical model based on the theory of technological paradigm, trajectory, and regime. Along with the process research methodology, the model is applied to the evolution of network in the computer and related industries. Starting with the very early ARPAnet to the NSFnet, and to the Internet, the analysis identifies the drivers of changes happened to products, industries, and markets. Theoretic propositions are projected based on the case research result.
