C To understand how revolutionary the Third Wave is, we ought to consider how far we have come. The First Wave began when companies started to manage their operations via mainframe computer systems over 50 years ago. Then computing got “personal” in the 1980s and 1990s with the introduction of the PC. For the most part, computing remained immobile and lacked contextual awareness. In the Second Wave of computing, mobile computing and the smartphone took center stage. Billions of people, some who might not have had access to clean water, electricity, or even housing, were connected. Developers created apps and provided consumers with access to just about everything through their phones at the cost of a monthly data plan. As the Third Wave gains momentum, designers must meet the demands of clients who want to experiment with new technology. 1. In the First Wave of computing,_______________ .
