Professor Jensen addressed the emergence of “network economics” and its implication on the market and firm decision-making. Facebook, Face Time, fax machines, PS3 and Apple products are all examples of direct and indirect network externalities. Network industries tend to tip toward monopoly; no one is switching to Google+ when everyone else is using Facebook, and you are not going to buy Nintendo games when you have a PS3 station. Firms thus recognize the importance of early acquisition of customers, leading to dynamic competition in the R&D department. Once a network is established, firms ask what they can do to tip it over to another network.
