Facebook was once almost sold to Yahoo! for $1B, but Mark Zuckerberg refused the sale.

In 2006, Yahoo tried to buy Facebook for $1B. Despite enthusiasm from nearly all of Facebook's management team and board (which included PayPal cofounder and famed investor Peter Thiel at the time), then 22-year-old Zuckerberg turned down the offer, insisting that Yahoo undervalued the company and didn't have a clear vision for the future. Zuckerberg has since said he regrets not being clear about his intentions to grow the company with his team before the Yahoo bid, as almost all of the company's management team left after he turned down the offer.

Before becoming the head of OpenAI, Sam Altman was the president of Y Combinator—a startup accelerator company that supported companies like Airbnb, DoorDash, and Coinbase. In 2016, Altman interviewed Zuckerberg about creating Facebook and its growth over time. Zuckerberg said that, unlike other companies (think: CourseMatch), Facebook kept growing and adding new features, which prevented the app from becoming obsolete.

Mark Zuckerberg and Adam D'Angleo built a website called "Synapse," which created playlists for users based on their listening preferences and an algorithm to suggest new songs, in September 2002.

While at Harvard, three students (Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra) approached Mark Zuckerberg with the idea for a platform exclusively for Harvard students called ConnectU. Those students sued Facebook, alleging that Zuckerberg stole the idea from the trio.

The phrase was plastered across Facebook's office as a representation of the company's hacker mindset that fueled its early growth. However, Zuckerberg said he has since moved away from that motto and has focused more on sustainability as opposed to breakneck growth.

Mark Zuckerberg enrolled in Harvard in 2002 and studied computer science and psychology. He officially dropped out in 2005 to run Facebook, now Meta. When he returned to campus to officially drop out, he met with professors and students to recruit programmers for the company.

Within 24 hours of launching in 2004, more than 1,200 Harvard students signed up to the platform, which quickly expanded to other Ivy League and Boston-area schools within months. By year's end, Zuckerberg left Harvard to run the company in California.

During Mark Zuckerberg's sophomore year at Harvard, he built a website that allowed users to rank and rate people's pictures from the school's online "facebooks" called Facemash.com, which quickly went viral. He was placed on academic probation for violating the school's rules around data, privacy, and computer usage. Zuckerberg says the website was a prank and he never intended for so many people to see it. FaceMash is credited with being the predecessor to Facebook.

A whistleblower came forward with internal documents showing employees warned leadership about the company's role in fueling political unrest and misinformation. Systems like XCheck shielded high-profile users like President Donald Trump from normal content rules, often to avoid PR backlash.

Peter Thiel was Facebook's first big investor. In 2004, he invested $500K into the social network, long before the company owned Instagram or renamed itself "Meta." In 2012, when he sold off most of his stake, he turned that initial $500K investment into more than $1B in cash.

Zuckerberg, like Apple cofounder Steve Jobs, wore the same, simple T-shirts and outfits for most of his early career to decrease the decisions he'd have to make on a daily basis. In 2024, Zuckerberg started wearing chunky gold chains around his neck and oversized T-shirts with slogans on them. Some say the "Zuckassaince" is an effort to rebrand Meta as a futuristic company, not just an old social media company for millennials.

Mark Zuckerberg grew up in Dobbs Ferry in Westchester County, about 25 miles north of New York City. His father, Ed Zuckerberg, owned a practice connected to Mark's childhood home, but he was always fascinated by computers. Ed's family was the first in his neighborhood to have a color television, and Ed was an early adopter of computing technology—something that he passed on to Mark.

Zuckerberg testified in Congress for the first time in 2018 over Facebook's privacy violations and its failure to detect Russian interference on the app during the 2016 election.

Despite Meta's core products being social media apps, Zuckerberg is adamant that Meta is a technology company that has built social media apps, but can build and is comfortable building other technologies—like AI-integrated glasses and virtual reality labs.

Meta has a dual-class stock structure, meaning there are two types of stock that have different voting rights. Zuckerberg owns 90% of the company's Class B stock, which is allotted 10 votes per share, whereas Class A shareholders get one vote per share. He's also the CEO and the chairman of the board, meaning Zuckerberg has majority control over the company.

Facebook has been criticized for years for a prevalence of disinformation and hate speech, a problem that's not just confined to digital content. The plaintiffs argue Facebook's algorithm amplified dangerous propaganda in Myanmar, contributing to violence.

After giving birth to their daughter, the Zuckerbergs launched the Chan Zuckerberg Initiative in 2015. The pair announced the charitable organization's creation in a letter addressed to their daughter. The Zuckerbergs pledged 99% of their earnings from Facebook over the course of their lives to advance education, cure disease, and transform public policy, something the letter says is a commitment to their daughter's future. The organization has since shifted its focus to artificial intelligence and science.

Randi is two years older than Mark and also attended Harvard before working in advertising. Before joining Facebook, Randi worked in digital advertising at Ogilvy & Mather.

She's also previously been criticized for her own seemingly contradictory sentiments on Facebook's privacy rules.

Meta, back when the company was still known as Facebook, once tried and failed to launch a smartphone. With the arrival of the mixed reality era, the company decided to make another hardware play again—and this time, it's having better luck. Meta's aggressively priced Quest headsets offer VR for the masses, and here CEO Mark Zuckerberg shows off the new mixed reality experiences and more available with the latest version, the Quest 3.

During the pandemic, Zuckerberg began practicing Brazilian jiu-jitsu and even won gold and silver medals at his first tournament in 2023. His interest in martial arts and water sports, like wakesurfing and hydrofoiling, prompted the company to disclose those hobbies as risks for potential investors, given they pose a threat to Zuckerberg's health and he retains a significant amount of control over Meta.

He admits the company made many mistakes during its growth from 100 Google employees to nearly 200,000 in 2022. His biggest mistake as CEO involved social media, which was not executed well with the Google+ platform.

Cuban co-founded AudioNet with Todd Wagner in 1995 before it became Broadcast.com—a web app that allowed people to listen to sports commentary on their computers if they couldn't watch a game. In 1999, Yahoo bought Broadcast.com for $5.7B. By the time the market crashed, Cuban had already sold most of his stock in the company and had become a billionaire.

The controversial "FaceMash," where students rated each other's attractiveness, was the precursor to Mark Zuckerberg's social network. The platform rebranded as Meta after several acquisitions and a push into virtual reality, distancing itself from controversies.

Investigative journalists have written that social platform X's open, sometimes chaotic workplace stopped when control shifted irreversibly from Jack Dorsey to Elon Musk. They claim the stark contrast in personalities left little protection for existing employees, culture, or users.

Leading up to the 2016 election, misinformation about both Donald Trump, Hillary Clinton, and even Barack Obama flourished on Facebook. In the final stretch leading up to the election, more than one-quarter of Americans visited a fake news site supporting either Trump or Clinton. Many fake news studies have widely different methods of measuring and assessing the impact of fake news, so the actual impact it had in the 2016 election is unclear.

In Zuckerberg's 2017 commencement speech at Harvard, Zuckerberg said his best memory at Harvard was meeting Priscilla Chan in line for the bathroom at a party. In that speech, he said he told her, "I'm going to get kicked out in three days, so we need to go on a date quickly." The pair got married in 2012 and now have three kids together.

The short-term rental CEO learned hard lessons through the pandemic, specifically around a culture focused on management and not building products.

Over the years, Amazon founder Jeff Bezos often recalls how wrong the predictions in the 1999 Barron’s cover story were. Among other things, that article declared Amazon’s entire business model to be unsustainable and destined to fail, noting its lack of profit and dependence on a massive amount of capital to fund its growth.

The CEOs of top technology companies Nvidia and Meta recently revealed their visions for the metaverse of the future. As of 2021, both Jensen Huang and Mark Zuckerberg were bullish on virtual world-building, although Huang seemed more focused on the metaverse's business implications than its social ones, which Zuckerberg prioritized.

Moving beyond the controversies over fueling misinformation, division, and harm worldwide, Mark Zuckerberg expressed optimism about technology's role in connecting people. Meta's multibillion-dollar investments in integrative AR and VR technologies have further evolved its founder's vision.

In 2020, the Federal Trade Commission sued Meta as part of the agency's efforts to rein in big tech companies. The FTC alleged that Meta overpaid for Instagram and WhatsApp in a "buy or bury" strategy to gain access to those companies' talent and diminish competition. In 2025, a federal judge sided with Meta, citing intense change in the social media landscape.

What began in early 2022 as Musk quietly buying Twitter shares soon escalated into a $44 billion hostile bid to take the company private. When Musk officially took over Twitter, he walked into headquarters carrying a literal kitchen sink, captioning the moment, "Let that sink in."

Airbnb is arguably known as one of the most successful startup stories of all time. But back in 2008, many prominent investors rejected their pitch when they went out to raise money—and Airbnb's founder still has the rejection emails to prove it.

In a 1999 shareholder letter, Bezos wrote, "I constantly remind our employees to be afraid, to wake up every morning terrified. Our customers have made our business what it is, and we consider them to be loyal to us – right up until the second that someone else offers them a better service." Motivated by fear, the entrepreneur advocates consistent innovation, experimentation, and improvement to create a better customer experience.

Bezos parlayed a career on Wall Street into founding an online bookstore that would evolve into the largest online retailer in the world. Bezos’ story is characterized by his relentless focus on innovation and on the customer experience at Amazon.

When Jesse Eisenberg hosted "SNL" in 2011 ahead of an Academy Awards appearance for his portrayal of Zuckerberg in "The Social Network," Zuckerberg actually came on stage.
