'Understanding New Media' is a necessary and up to date upgrade of Marshall McLuhan's theories in the context of a new digital media ecology. Bob Logan is one of the best interpreters of McLuhan's 360 vision of media, technology and culture, and he has enriched this wide- angle perspective by including categories from biology, complexity and evolution fields. In a historical moment characterized by a hyper- specialization of science - media studies are not the exception - this integrated approach is essential for understanding new media. (Carlos A. Scolari, Professor, Pompeu Fabra University, Barcelona) Marshall McLuhan's ideas on media have stood the test of time remarkably well. In many respects they are more relevant today than in the time of writing. Thus, an update of his classic work 'Understanding Media' from 1964 makes perfect sense. And I could think of no better candidate for the task than Robert Logan. His first-hand knowledge of McLuhan combined with his straightforward and lucid style of writing makes 'Understanding New Media' extremely useful as a guide to McLuhan's thoughts as well as our present world of 'New Media'.
