THE NEW YORK TIMES BOOK REVIEW EDITORS’ CHOICE • By an award-winning technology reporter for The Wall Street Journal, a behind-the-scenes look at the manipulative tactics Facebook used to grow its business, how it distorted the way we connect online, and the company insiders who found the courage to speak out

"Broken Code fillets Facebook’s strategic failures to address its part in the spread of disinformation, political fracturing and even genocide. The book is stuffed with eye-popping, sometimes Orwellian statistics and anecdotes that could have come only from the inside." —New York Times Book Review

Once the unrivaled titan of social media, Facebook held a singular place in culture and politics. Along with its sister platforms Instagram and WhatsApp, it was a daily destination for billions of users around the world. Inside and outside the company, Facebook extolled its products as bringing people closer together and giving them voice.

But in the wake of the 2016 election, even some of the company’s own senior executives came to consider those claims pollyannaish and simplistic. As a succession of scandals rocked Facebook, they—and the world—had to ask whether the company could control, or even understood, its own platforms.

Facebook employees set to work in pursuit of answers.  They discovered problems that ran far deeper than politics. Facebook was peddling and amplifying anger, looking the other way at human trafficking, enabling drug cartels and authoritarians, allowing VIP users to break the platform’s supposedly inviolable rules. They even raised concerns about whether the product was safe for teens. Facebook was distorting behavior in ways no one inside or outside the company understood. 

Enduring personal trauma and professional setbacks, employees successfully identified the root causes of Facebook's viral harms and drew up concrete plans to address them. But the costs of fixing the platform—often measured in tenths of a percent of user engagement—were higher than Facebook's leadership was willing to pay. With their work consistently delayed, watered down, or stifled, those who best understood Facebook’s damaging effect on users were left with a choice: to keep silent or go against their employer.

Broken Code tells the story of these employees and their explosive discoveries. Expanding on “The Facebook Files,” his blockbuster, award-winning series for The Wall Street Journal, reporter Jeff Horwitz lays out in sobering detail not just the architecture of Facebook’s failures, but what the company knew (and often disregarded) about its societal impact. In 2021, the company would rebrand itself Meta, promoting a techno-utopian wonderland. But as Broken Code shows, the problems spawned around the globe by social media can’t be resolved by strapping on a headset.

NAMED A PORCHLIGHT BOOKS BEST BUSINESS BOOK OF THE YEAR

"Broken Code fillets Facebook’s strategic failures to address its part in the spread of disinformation, political fracturing and even genocide. The book is stuffed with eye-popping, sometimes Orwellian statistics and anecdotes that could have come only from the inside."
—New York Times Book Review

"Broken Code offers a comprehensive, briskly reported examination of key systems governing [Facebook] and their many failings... A smartly reported investigation into the messy internal machinations of one of the world’s most important and least understood companies."
—Washington Post

“Jeff Horwitz has written a blockbuster expose of Facebook, the notoriously secretive social media giant whose benign mission—connecting people—masked a growing propensity towards some of humanity’s worst impulses. Populated by concerned, brave employees who defied their employer and leaked thousands of pages of internal documents to Horwitz, with the imperious, remote Mark Zuckerberg and his top lieutenants at the center, Broken Code is brilliant reporting and a page-turning narrative of immense importance.”
—James B. Stewart, Pulitzer Prize-winning investigative journalist and New York Times bestselling author

“A dogged and meticulous reporter, Jeff Horwitz is at the height of his powers in Broken Code, a penetrating portrait of one of the most significant companies in the world and of one of the great new challenges of this technological era.”
—Ronan Farrow, Pulitzer Prize-winning investigative journalist and New York Times bestselling author

"An unsettling account….Stories of executives bumbling their way through or outright ignoring issues within the company are breathtaking and troubling… Horwitz’s reporting shines...This convincingly makes the case that Facebook’s pursuit of growth at any cost has had disastrous offline consequences."
—Publishers Weekly

"Readers interested in the ethics of the internet and technology, the business aspects of social media, and social media's impact on society at large will be fascinated. Horwitz has created an essential resource."
—Booklist

"A well-researched, disturbing study of a tech behemoth characterized by arrogance, hypocrisy, and greed." 
—Kirkus Reviews

"Impressive reporting... A thoroughly documented portrait of a company that recognizes its products have harmed people yet declines to meaningfully change them."
—San Francisco Chronicle
