One caveat, though: It is extremely difficult to cross the chasm in a consumer market. Almost all successful crossings happen in business markets, where the economic and technical resources can absorb the challenges of an immature product and service offering. Alternatively, consumer markets can spin up with no chasms at all if the technology is already adopted and the disruption is coming from a new business model. (For an alternative market development model that describes these dynamics, see “The Four Gears” discussion in Appendix 2.)
