Steve Wozniak aka “The Woz” learned about phreaking from the 1971 Esquire article “Secrets of the Little Blue Box” by Ron Rosenbaum. Halfway through the article, Woz called his friend, Steve Jobs, and read it to him. They were fascinated by the exploits of Joybubbles, Captain Crunch, and the underground telephone hackers who were whistling their way into Ma Bell (AT&T).

Cybercrime Magazine writes:

Woz and Jobs went on to make history by building a blue box, which was digital and more technologically advanced compared to the electronics analog models being used by phone phreaks at that time. “What a trip that was,” says Woz. “I had tricks in there that I never even equaled in my Apple designs, believe it or not.”
