This book is about the leading entrepreneurs and thinkers who contributed to the digital revolution. I love that it begins with Ada Lovelace, the first programmer, and goes all the way up to Al Gore. I found this book illuminating. It's written in a unified sequential narrative that makes the progression of innovation over long periods of time easy to understand. Walter Isaacson also wrote Steve Jobs' biography. I recommend this book to anyone who wants a better understanding of digital innovation and they types of entrepreneurs who have had the most success in this field.
