Crossing the Chasm (1991) and Inside the Tornado (1995) aremost valuable when read in combination. Chasm "is unabashedly aboutand for marketing within high-tech enterprises." It was written forthe entire high tech community "to open up the marketing decision making during this [crossing] period so that everyone on the management team can participate in the marketing process." In Chasm, Moore isolates and then corrects what he describes as a "fundamental flaw in the prevailing high-tech marketing model": the notion that rapid mainstream growth could follow continuously on the heels of early market success. In his subsequent book, Inside the Tornado, Moore's use of the "tornado" metaphor correctly suggests that turbulence of unprecedented magnitude has occurred within the global marketplace which the WWW and the Internet have created. Moreover, such turbulence is certain to intensify. Which companies will survive? Why? I have only one (minor) quarrel with the way these two books have been promoted. True, they provide great insights into marketing within the high technology industry. However, in my opinion, all e-commerce (and especially B2B) will be centrally involved in that industry. Moreover, the marketing strategies suggested are relevant to virtually (no pun intended) any organization -- regardless of size or nature -- which seeks to create or increase demand for what it sells...whatever that may be. I consider both books "must reading."
