The Web has evolved from its humble beginnings merely as a publishing medium intended for a small group of scientists to a medium of interaction, participation, and collaboration. It has dramatically influenced almost every sphere of our activity and has created paradigm shifts. Encompassing new technologies, business strategies, and social trends, the Web continues to forge many new applications that we had never imagined before or were not previously feasible. It has created new paradigms in business, social interaction, governance, and education. In this chapter, we trace the Web’s continuing evolution and phenomenal strides, outline the features and characteristics of Web 2.0, 3.0, and X.0, and examine their prospects and potential. The ability to recognize new Web technologies for their potential in business, social and educational applications, and the ability to develop and deploy creative applications based on these technologies are the keys to continued success of the Web and our progress and well being.
