Notes

Facebook was drawn mostly from more than three hundred interviews of company employees past and present as well as knowledgeable outsiders who had direct interaction with the people and events in the book. (Unless otherwise noted, direct quotes in the book come from those interviews.) I benefited from the work of David Kirkpatrick, who wrote the definitive history of the company’s early years: The Facebook Effect: The Inside Story of the Company That Is Connecting the World (Simon & Schuster, 2010). An invaluable resource was the Zuckerberg Files (zuckerbergfiles.org), a comprehensive source of more than one thousand interviews and videos, administered by Michael Zimmer. And Casey Newton’s daily newsletter, The Interface, always kept me apprised of the latest twists in the Facebook story.

Harpaz, “Dr. Zuckerberg Talks about His Son’s Upbringing,” Associated Press, February 4, 2011. Other useful accounts of early Mark Zuckerberg include two New Yorker profiles: Jose Antonio Vargas, “The Face of Facebook,” The New Yorker, September 13, 2010; and Evan Osnos, “Can Mark Zuckerberg Fix Facebook Before It Breaks Democracy?” The New Yorker, September 10, 2018.

CHAPTER TWO: Ad-Boarded

Zuckerberg’s Harvard years are voluminously documented, though often different agendas are at play. Besides personal interviews, some of the more consistently useful sources were The Facebook Effect, the published excerpts from depositions in the ConnectU case, the excellent coverage in the Harvard Crimson, and many comments from Zuckerberg himself in various interviews in the Zuckerberg Files.

“I am not even sure”: The Human Code with Laurie Segall podcast, February 4, 2019.

His formal acceptance: Zuckerberg shared the video on Facebook, May 18, 2017.

Paul Ceglia: The Ceglia v. Zuckerberg court filing provides the information about the $1,000 fee. After the suit was dismissed because Ceglia allegedly forged the document that was his claim to owning Facebook, Ceglia fled to Ecuador to avoid prosecution. As of June 2019, the United States has been unable to extradite him. Bob Van Voris, “Facebook Fugitive Paul Ceglia’s Three Years on the Run,” Bloomberg, November 10, 2018; and David Cohen, “Ecuador Won’t Return Fugitive and Former Facebook Claimant Paul Ceglia to the U.S.,” Adweek, June 25, 2019.

Seth Feigerman’s “Friendster Founder Tells His Side of the Story” (Mashable, February 3, 2014) gives Abrams’s point of view. There are also good summaries in Angwin’s Stealing MySpace and Kirkpatrick, The Facebook Effect.

CHAPTER THREE: Thefacebook

ConnectU: There is an entire subgenre of journalism (and cinema!) devoted to the dispute between Zuckerberg and his classmates. Some of the most reliable accounts came under oath in depositions unearthed first by Luke O’Brien, “Poking Facebook,” 02138 magazine, November–December 2007. Ben Mezrich’s book The Accidental Billionaires: The Founding of Facebook (Doubleday, 2009) has a number of firsthand documents. Nicholas Carlson’s reporting in Business Insider yielded hitherto unknown instant messaging and emails, as well as valuable reporting. Kirkpatrick’s The Facebook Effect, as always, was solid on the issue.

CHAPTER FOUR: Casa Facebook

Sean Parker: The Parker background is drawn from multiple sources, including a weeklong reporting trip I spent with him in 2011. Joseph Menn gives an excellent mini-biography, and besides The Facebook Effect, Kirkpatrick wrote a profile of Parker for Vanity Fair (“With a Little Help from His Friends,” November 2010). Also see Steven Bertoni, “Agent of Disruption,” Forbes, September 21, 2011.

CHAPTER THIRTEEN: Buying the Future

Kevin Systrom recalls: The section about Instagram’s early days was drawn from a number of sources.

Key published sources were Kara Swisher, “The Money Shot,” Vanity Fair, May 6, 2013; Somini Sengupta, Nicole Perlroth, and Jenna Wortham, “Behind Instagram’s Success, Networking the Old Way,” New York Times, April 13, 2012; and Mike Krieger, “Why Instagram Worked,” Wired, October 20, 2014.

a review from the FTC: Josh Kosman, “Facebook Boasted of Buying Instagram to Kill the Competition: Sources,” New York Post, February 26, 2019.

Snapchat: In addition to interviews, I drew on Billy Gallagher’s definitive book, How to Turn Down a Billion Dollars (St. Martin’s Press, 2018). Also valuable was Sarah Frier and Max Chafkin, “How Snapchat Built a Business by Confusing Olds,” Bloomberg BusinessWeek, March 17, 2016; J. J.

“Project Voldemort”: Georgia Wella and Deepa Seetharaman, “Snap Detailed Facebook’s Aggressive Tactics in ‘Project Voldemort’ Dossier,” Wall Street Journal, September 24, 2019.

a messaging company called WhatsApp: In addition to personal interviews, I drew background on WhatsApp from a number of sources. Parmy Olsen’s work for Forbes is best on its history up to the Facebook purchase: “EXCLUSIVE: The Rags-to-Riches Tale of How Jan Koum Built WhatsApp into Facebook’s New $19 Billion Baby,” February 19, 2004; and “Inside the Facebook-WhatsApp Megadeal: The Courtship, the Secret Meetings, the $19 Billion Poker Game,” March 4, 2014.

Oculus: The definitive book on Oculus is Blake Harris, The History of the Future (Dey Street, 2019). It is particularly valuable for its wealth of original documents and emails. All the principals in the company, as well as those from Facebook, testified in the January 2017 Zenimax v. Facebook et al, trial in Texas, and I drew from those transcripts, as well as personal interviews.

“Have you seen Oculus?”: The emails among parties in and out of Facebook were made public via the Zenimax litigation. All are reprinted in the Harris book.

Other sources in addition to personal interviews include Michael Isikoff and David Corn, Russian Roulette: The Inside Story of Putin’s War on America and the Election of Donald Trump (Twelve, 2018); and David E. Sanger, The Perfect Weapon: War, Sabotage, and Fear in the Cyber Age (Crown, 2018).

This is the explosive story that revealed much of the behind-the-scenes machinations in Facebook’s policy world during and after the 2016 election.

the CEO allowed it to stay: Seetharaman, “Facebook Employees Pushed to Remove Trump’s Posts.”

“news curator”: Michael Nunez, “Former Facebook Workers: We Routinely Suppressed Conservative News,” Gizmodo, May 9, 2016.

The story in general provides a deep inside view of Facebook in 2016 and 2017.

mini-documentary: In a 2018 Wired story, Antonio García Martínez, a former Facebook ad executive, wrote about how the Trump campaign got more value from Facebook than the Clinton campaign, in “How Trump Conquered Facebook—Without Russian Ads,” Wired, February 23, 2018. Facebook’s Andrew Bosworth responded on Twitter with data that seemed to indicate the Trump campaign actually paid more per million views. This was disputed by Trump’s digital director, who claimed that in some cases, Trump was getting a hundred times more value per CPM. Will Oremus in Slate (“Did Facebook Really Charge Clinton More for Ads than Trump?” February 28, 2018) found that while Bosworth might be technically correct, the larger advantage was Trump’s because the Clinton campaign used less effective general interest ads while the Trump digital team ran more narrowly targeted “call to action” ads that indeed got more bang for the buck. As for the two-and-a-half minute ad, I was unable to locate that example but included it, as the source had firsthand knowledge of the episode. Later, Facebook conceded that the data showed the Trump campaign’s superiority in this realm (Sarah Frier, “Trump’s Campaign Says It Was Better at Facebook. Facebook Agrees,” Bloomberg Businessweek, April 3, 2018).

Parscale understood: Useful sources for the Parscale campaign were Issie Lapowsky, “The Man Behind Trump’s Bid to Finally Take Digital Seriously,” Wired, August 19, 2016; Joshua Green and Sasha Issenberg, “Inside the Trump Bunker with Days to Go,” Bloomberg BusinessWeek, October 27, 2016; Sue Halpern, “How He Used Facebook to Win,” New York Review of Books, June 8, 2017; and Leslie Stahl (correspondent), “Brad Parscale,” 60 Minutes, October 18, 2017.

Parscale began directing: A good explanation of how Parscale used Facebook’s tools comes from Martínez, “How Trump Conquered Facebook.”

Dave Goldberg was dead: Sandberg’s own account is in her book, co-written with Adam Grant, Option B: Facing Adversity, Building Resilience, Finding Joy (Knopf, 2017). She discussed the loss and its consequences in interviews including Belinda Luscombe, “Life After Grief,” Time, April 13, 2017; Jessi Hempel, “Sheryl Sandberg’s Accidental Revolution,” Backchannel, April 24, 2017.

prone to yelling at subordinates: This was described to me by multiple employees who worked with Sandberg.

obsessed with her public image: Besides personal interviews, Sandberg’s image tending has been written about in the aftermath of Facebook’s problems. See Nick Bilton, “‘I Hope It Cracks Who She Is Wide Open’: In Silicon Valley, Many Have Long Known Sheryl Sandberg Is Not a Saint,” Vanity Fair, November 16, 2018. The aforementioned New York Times article, “Delay, Deny and Deflect,” which portrays Sandberg as culpable in the post-election saga, was a turning point in the press’s treatment of the COO.
