50 years of Apple

Why Apple wouldn’t exist without the Blue Box

In 1971, a high school student and a college student built an illegal device that tricked AT&T’s telephone network. Steve Jobs and Steve Wozniak had no idea that they were laying the foundation for one of the most valuable companies in the world.
A magazine article, a few electronic components and two young men with a shady business model – that’s how Apple’s story begins.
This article is part of our series celebrating Apple’s 50th anniversary. You can find the list of all articles here:
An idea that stuck
It’s October 1971 and 21-year-old Steve Wozniak, student of electronics at the University of California, Berkeley, reads an article in the Esquire (page in German). The text, Secrets of the Little Blue Box, describes how phone phreaks – the first playful hackers – manipulated the AT&T telephone network using homemade devices to make free long-distance calls. Back then, a single phone call often cost an entire day’s wages.
John T. Draper, known as Captain Crunch, is the man behind the discovery. He figures out that a plastic whistle included in Cap’n Crunch cereal boxes produces exactly the right sound to fool AT&T’s system.
Wozniak decides to build a more precise version of the device he saw in the magazine. It works – and with that, a story begins that goes far beyond an illegal phone gadget.
Two Steves, one vision
Through a mutual friend, Wozniak meets Steve Jobs, who’s five years his junior – a high school student with an impeccable business sense. Wozniak solves technical puzzles while Jobs spots opportunities. Wozniak remembers how «Steve had this way of seeing the bigger picture». «Where I saw a cool engineering puzzle, he saw a business opportunity. That was the magic of our partnership from day one.»
The art of sales
Jobs and Wozniak begin working on their sales strategy. Jobs as the businessman, Wozniak as the tech wizard. Together, they go around university dorms and demonstrate their invention. «Name one place in the world,» Jobs challenges potential customers. «Anywhere.»
London. Tokyo. Moscow. A few seconds later, the international dial tone sounds. Jobs later told his biographer Walter Isaacson that they had this «routine down perfect» and «together we were unbeatable».
But things weren’t always smooth. One time, they demonstrated the box in a pizzeria and caught the attention of a police officer. «My heart was pounding so hard, I thought it was going to jump out of my chest,» Wozniak recalls. «Steve, cool as ever, just slid it into his pocket, and kept talking like nothing was happening.»
A lesson for Apple
The two of them go on to sell the boxes to their friends – a lucrative side hustle for students. But the true value was lying elsewhere. «Two teenagers were able to build a box for a hundred dollars and use it to control an infrastructure worth several hundred billion dollars – the entire global telephone system. That’s where the magic happened,» raved Jobs. Wozniak often recounts the time he demonstrated how it worked by calling the Pope pretending to be U.S. Secretary of State Henry Kissinger.
Later, Jobs was very clear about what this meant: «If we hadn’t made blue boxes, there would have been no Apple. We gained the confidence that we could solve technical problems and actually put something into production.»
The lessons from the Blue Box era read like a blueprint for Apple: Wozniak’s technical brilliance meets Jobs’ ingenious ideas. His talent for dramatic presentations – which would later become a hallmark of every Apple keynote – was already evident back then.
The starting signal for Apple
On 1 April 1976 Jobs and Wozniak founded Apple. Their products were designed to revolutionise the way we interact with technology. Hardly anyone knows that it all started with two young men and a small blue box. In fact the idea that the company was founded in his parents’ garage is a myth, as Wozniak himself says here:
Jobs put it aptly in his Stanford speech in 2005: «You can’t connect the dots looking forward. You can only connect them looking backward. You have to trust that they’ll come together eventually.»
Apple is now one of the most valuable technology companies in the world. Looking back, the key milestones in the company’s history have fallen into place perfectly. And it all started with the Blue Box.
