Problem:
Technological paradigm shifts happen all the time. One example is the telecommunications industries in developing countries, where consumers are choosing to adopt wireless technology before wired technology, reversing the process in developed nations. Another good example would be the handheld communications industry, where cell phones can now act like computers or Internet browsers, in addition to their other functions.
