Tom McNichol interviews Ron Rosenbaum about his 1971 Esquire story on an early network of hackers who built "blue boxes" to make free phone calls: "Rosenbaum’s article is the rare magazine story that not only chronicled history, it also shaped it. A tech enthusiast named Steve Wozniak read Rosenbaum’s piece, and then showed it to his friend Steve Jobs. Before long, the two collaborated on building and selling their own blue boxes."
