Slate has reprinted the piece that Ron Rosenbaum wrote for Esquire
in 1971, explaining to the world that there was an underground movement of people hacking the phone system. (Rosenbaum is now a columnist for Slate.) According to the article's new introduction and followup piece by Rosenbaum reflecting on its impact
— and to the New York Times obituary for Steve Jobs — this article inspired Jobs and Wozniak to start building blue boxes themselves, an effort that made them several thousand dollars.
