Abstract
In this paper we set out to investigate E-learning industry in the United States from 1998 to 2001. Research focus is to put on the firms' exploratory process for setting their business models. To comprehend the industrial performance, we propose our taxonomy attempting to identify the firms' selection of how to combine learning contents (domain knowledge) with their general knowledge on information technologies. We undertake database analysis on 73 US firms and present the systematization of emerging business models from our taxonomies. Our results indicate that business studies on E-learning firms benefit from the taxonomical analysis based on knowledge management, providing some managerial recommendation for the business.
