over the age of thirteen with a valid email address. News Feed is the heart of the Facebook user experience, and it is hard today to imagine that the site did well for a couple of years without it. Then, in January 2007, Facebook introduced a mobile web product to leverage the widespread adoption of smartphones. The desktop interface also made a big leap.
In the summer of 2007, Zuck called to offer me an opportunity to invest. He actually offered me a choice: invest or join the board. Given my profession and our relationship, the choice was easy. I did not need to be on the board to advise Zuck. The investment itself was complicated. One of Facebook’s early employees needed to sell a piece of his stake, but under the company’s equity-incentive plan there was no easy way to do this. We worked with Facebook to create a structure that balanced both our needs and those of the seller. When the deal was done, there was no way to sell our shares until after an initial public offering. Bono, Marc, and I were committed for the long haul.
Later that year, Microsoft bought 1.6 percent of Facebook for $240 million, a transaction that valued the company at $15 billion. The transaction was tied to a deal where Microsoft would sell advertising for Facebook. Microsoft paid a huge premium to the price we paid, reflecting its status as a software giant with no ability to compete in social. Facebook understood that it had leverage over Microsoft and priced the shares accordingly. As investors, we knew the Microsoft valuation did not reflect the actual worth of Facebook. It was a “strategic investment” designed to give Microsoft a leg up over Google and other giants.
Soon thereafter, Facebook launched Beacon, a system that gathered data about user activity on external websites to improve Facebook ad targeting and to enable users to share news about their purchases. When a Facebook user interacted with a Beacon partner website, the data would be sent to Facebook and reflected in the user’s News Feed. Beacon was designed to make Facebook advertising much more valuable, and Facebook hoped that users would be happy to share their interests and purchase activities with friends. Unfortunately, Facebook did not give users any warning and did not give them any ability to control Beacon. Their activities on the web would appear in their Facebook feed even when the user was not on Facebook. Imagine having “Just looked at sex toys on Amazon.com” show up in your feed. Users thought Beacon was creepy. Most users did not know what Facebook was doing with Beacon. When they found out, they were not happy. Zuck’s cavalier attitude toward user privacy, evident from the first day of Facemash back at Harvard, had blown up in his face. MoveOn organized a protest campaign, arguing that Facebook should not publish user activity off the site without explicit permission. Users filed class action lawsuits. Beacon was withdrawn less than a year after launch.
In the fall of 2007, Zuck told me he wanted to hire someone to build Facebook’s monetization. I asked if he was willing to bring in a strong number two, someone who could be a chief operating officer or president. He said yes. I did not say anything, but a name sprang to mind immediately: Sheryl Sandberg. Sheryl had been chief of staff to Secretary of the Treasury Larry Summers during Bill Clinton’s second term. In that job, she had partnered with Bono on the singer’s successful campaign to spur the world’s leading economies to forgive billions in debt owed by countries in the developing world. Together, Bono and Sheryl helped many emerging countries to reenergize their economies, which turned out to be a good deal for everyone involved. Sheryl introduced Bono to me, which eventually led the two of us to collaborate on Elevation Partners. Sheryl came to Silicon Valley in early 2001 and hung out in my office for a few weeks. We talked to Sheryl about joining Integral, but my partner John Powell had a better idea. John and I were both convinced that Sheryl would be hugely successful in Silicon Valley, but John pointed out that there were much bigger opportunities than Integral. He thought the right place for Sheryl was Google and shared that view with John Doerr, who was a member of Google’s board of directors. Sheryl took a job at Google to help build AdWords, the product that links ads to search results.
AdWords is arguably the most successful advertising product in history, and Sheryl was one of the people who made that happen. Based on what I knew about Sheryl, her success came as no surprise. One day in 2007, Sheryl came by to tell me she had been offered a leadership position at The Washington Post. She asked me what I thought. I suggested that she consider Facebook instead. Thanks to Watergate and the Pentagon Papers, the Post was iconic, but being a newspaper, it did not have a workable plan to avoid business model damage from the internet. Facebook seemed like a much better match for Sheryl than the Post, and she seemed like the best possible partner for Zuck and Facebook. Sheryl told me she had once met Zuck at a party, but did not know him and worried that they might not be a good fit. I encouraged Sheryl to get to know Zuck and see where things went. After my first conversation with Sheryl, I called Zuck and told him I thought Sheryl would be the best person to build Facebook’s advertising business. Zuck worried that advertising on Facebook would not look like Google’s AdWords—which was true—but I countered that building AdWords might be the best preparation for creating a scalable advertising model on Facebook. It took several separate conversations with Zuck and Sheryl to get them to meet, but once they got together, they immediately found common ground. Sheryl joined the company in March 2008. Looking at a March 2008 Wall Street Journal article on Sheryl’s hire and Zuck’s other efforts to stabilize the company by accepting help from more experienced peers, I’m reminded that Facebook’s current status as a multibillion-dollar company seemed far from inevitable in those days. The article highlighted the company’s image problems and mentioned Zuck complaining to me about the difficulties of being a CEO. Still, growth accelerated.
The underlying technology of the disastrous Beacon project resurfaced in late 2008 as Facebook Connect, a product that allowed users to sign into third-party sites with their Facebook credentials. News of hacks and identity theft had created pressure for stronger passwords, which users struggled to manage. The value of Connect was that it enabled people to memorize a single, strong Facebook password for access to thousands of sites. Users loved Connect for its convenience, but it is not obvious that they understood that it enabled Facebook to track them in many places around the web. With the benefit of hindsight, we can see the costs that accompanied the convenience of Connect. I tried Connect on a few news sites, but soon abandoned it when I realized what it meant for privacy.
The data that Facebook collected through Connect led to huge improvements in targeting and would ultimately magnify catastrophes like the Russian interference in the 2016 election. Other users must have noticed that Facebook knew surprising things about them, but may have told themselves the convenience of Connect justified the loss of privacy. With Connect, Facebook addressed a real need. Maintaining secure credentials is inconvenient, but the world would have been better off had users adopted a solution that did not exploit their private data. Convenience, it turns out, was the sweetener that led users to swallow a lot of poison.
Facebook’s user count reached one hundred million in the third quarter of 2008. This was astonishing for a company that was only four and half years old, but Facebook was just getting started. Only seven months later, the user count hit two hundred million, aided by the launch of the Like button. The Like button soon defined the Facebook experience. “Getting Likes” became a social phenomenon. It gave users an incentive to spend more time on the site and joined photo tagging as a trigger for addiction to Facebook. To make its advertising valuable, Facebook needs to gain and hold user attention, which it does with behavior modification techniques that promote addiction, according to a growing body of evidence. Behavior modification and addiction would play a giant role in the Facebook story, but were not visible during my time as a mentor to Zuck, and I would not appreciate their significance until 2017.
It turns out everyone wants to be liked, and the Like button provided a yardstick of social validation and social reciprocity—packaged as a variable reward—that transformed social networking. It seemed that every Facebook user wanted to know how many Likes they received for each post, and that tempted many users to return to the platform several times a day. Facebook amplified the signal with notifications, teasing users constantly. The Like button helped boost the user count to 305 million by the end of September 2009. Like buttons spread like wildfire to sites across the web, and along with Connect enabled Facebook to track its users wherever they browsed.
The acquisition of FriendFeed in August 2009 gave Facebook an application for aggregating feeds from a wide range of
