Digination's core premise is that technology impacts everyone in many ways—socially, culturally, politically, and psychologically. Life in a digital nation is not simply a reality where humans utilize technology. Conversely, technology is an agent that affects people both individually and collectively as a society. Through a media ecologist's lens, MacDougall (Curry College) weaves theory, empirical data, and his own perspective into an account of technology and its influence on humankind. The volume, part of the publisher's "Communication Studies" series, is divided into 11 chapters. The author begins with an examination of the contributions of media theorist Marshall McLuhan, whose influence is evident throughout the work. The core of the book consists of seven chapters, each focusing on an individual technology. E-mail, blogs, search engines, personal music devices, podcasts, laptops, and eBay take their turn as subjects in this examination. Finally, an appendix of McLuhan tetrads or charts that visually represent the societal effects of individual technologies closes the book. An interesting, timely analysis of the human relationship with the machine. Summing Up: Recommended.
