In their 2007 bestseller, Wikinomics, Don Tapscott and Anthony Williams taught the world how mass collaboration was changing the way businesses communicate, compete, and succeed in the new global marketplace. But much has changed in three years, and the principles of wikinomics are now more powerful than ever. In this new age of networked intelligence, businesses and communities are bypassing crumbling institutions. We are altering the way our financial institutions and governments operate; how we educate our children; and how the health-care, newspaper, and energy industries serve their customers. In every corner of the globe, businesses, organizations, and individuals alike are using mass collaboration to revolutionize not only the way we work, but how we live, learn, create, and care for each other. Once again backed by original research, Tapscott and Williams provide vivid new examples of organizations that are successfully embracing the principles of wikinomics.
