The rise and fall of a number of dotcoms has attracted a lot of attention in business press, but there does not seem to have been any in depth study to understand the economic logic of dotcom businesses. A close analysis of these businesses would show that many of them actually do not have any sound business model. Many of their assumptions are questionable. This paper attempts to provide an explanation to it using original concepts such as latent want, zero customer dissatisfaction and customer dissatisfaction elimination chain. It is argues that many firms fumbled because they did not try to see whether there existed any customer dissatisfaction and subsequent need for a dot com firm to eliminate the dissatisfaction. It is also found that firms did not see their capabilities to provide overall positive value when they focused on eliminating dissatisfaction at one point.
