Love him or hate him, Mark Zuckerberg has changed how the world connects online. His rise from a Harvard dropout to a billionaire tech mogul is a story that inspires millions around the globe. But there’s more to his life than what meets the eye.
In this article, we’ll uncover 10 shocking and lesser-known facts about Mark Zuckerberg’s journey to building one of the most powerful companies on the internet — and how he continues to shape the digital future.
Who Is Mark Zuckerberg?
Mark Elliot Zuckerberg was born on May 14, 1984, in White Plains, New York. He grew up in a well-educated family and showed a strong interest in computers from an early age. By the time he was in middle school, he had already built software programs for fun.

He joined Harvard University in 2002 but dropped out in 2004 to work full-time on Facebook. That decision changed his life forever. Today, he is the Chairman and CEO of Meta Platforms, the parent company of Facebook, Instagram, WhatsApp, and Threads.
As of 2025, his estimated net worth is around $110 billion, making him one of the richest people in the world.
1. He Built Facebook in Just a Week
Yes, you read that right. In January 2004, Zuckerberg created “TheFacebook” from his Harvard dorm room in just one week. It was originally designed to help students connect and share with each other. Within 24 hours, 1,200 students had already signed up.
Today, Facebook has over 3 billion active users monthly.
2. He Was Almost Expelled From Harvard
Before Facebook, Zuckerberg created an app called Facemash, which allowed students to rate their classmates’ appearances. It quickly became controversial and was shut down by the university. He was nearly expelled for violating privacy rules. But that controversy led to the idea of a social network — Facebook.
3. He Turned Down Offers to Sell Facebook
In the early years, big tech companies like Yahoo and Microsoft offered Zuckerberg billions of dollars to buy Facebook. But he refused. In 2006, Yahoo reportedly offered $1 billion, but Zuckerberg believed in his vision and declined.
Today, Meta is worth over $800 billion.
4. He Only Takes One Dollar Salary
Despite being a billionaire, Mark Zuckerberg’s official salary is just $1 per year. This move is common among wealthy tech CEOs. He makes his fortune through Meta shares, not from a paycheck.
5. He Owns Over 4000 Acres of Land in Hawaii
Zuckerberg and his wife Priscilla Chan have bought over 4,000 acres of land in Hawaii, including beaches and farmland. The move has sparked some local controversy, but it shows how the billionaire is investing in private retreats and nature conservation.
6. He Speaks Fluent Mandarin
In 2014, Zuckerberg surprised the world when he gave a 20-minute speech in Mandarin Chinese at a university in Beijing. He learned the language to better connect with his wife’s family and explore business opportunities in China.
7. His Security Costs Are Over $25 Million a Year
According to financial reports, Meta spends more than $25 million every year on Zuckerberg’s personal security. This includes bodyguards, home protection, and private travel. Being the face of a global tech empire comes with its risks.
8. Meta Lost Over $100 Billion in a Single Year
In 2022, Zuckerberg made a bold move by rebranding Facebook as Meta, focusing on the metaverse — a 3D digital world. But the company lost over $100 billion in value within a year. Critics called it a failure, but Zuckerberg stuck to his long-term vision, saying, “This is the future.”
9. He Signed the Giving Pledge to Donate 99 Percent of His Wealth
In 2015, Zuckerberg and Priscilla Chan pledged to donate 99 percent of their Facebook shares to charitable causes over their lifetime. Through the Chan Zuckerberg Initiative, they invest in education, health, and equality around the world.
10. He Is a Fierce Competitor
Zuckerberg is known for his calm voice and robotic style, but inside, he is a highly competitive businessman. He aggressively bought or copied rival apps like Instagram, WhatsApp, and Snapchat features to dominate the market.
His strategy has kept Meta at the top, despite constant criticism and competition.

Controversies That Follow Him
Mark Zuckerberg is no stranger to controversy. Over the years, he has faced intense criticism on multiple issues:
- Data privacy: The Cambridge Analytica scandal revealed that Facebook data was used without user permission to influence elections.
- Fake news: Facebook has been blamed for spreading misinformation during key events like US elections and the COVID-19 pandemic.
- Mental health: Studies show that Instagram, owned by Meta, negatively affects teen mental health.
- Monopoly power: Meta has been accused of crushing smaller companies and creating a monopoly in the tech world.
Despite these issues, Zuckerberg has remained in power and continues to reshape Meta’s direction.
The Metaverse Dream
Zuckerberg believes the metaverse is the next internet. He imagines a future where people will work, meet, and play inside a 3D digital world using virtual reality (VR) and augmented reality (AR).
Meta has already invested tens of billions of dollars in this vision, but results are still slow. Many believe it’s too early, while others see it as revolutionary.
Will Zuckerberg succeed in creating the next big thing? Only time will tell.
Zuckerberg’s Personal Life
Mark married Priscilla Chan, a doctor and philanthropist, in 2012. The couple met at Harvard and now have three children. They live a relatively private life and are known for their simple lifestyle despite their massive wealth.
Zuckerberg wears the same style of gray t-shirts every day to avoid “decision fatigue.” He believes that fewer small choices help him focus on more important decisions.
Conclusion: Mark Zuckerberg’s Legacy
Mark Zuckerberg is one of the most important people of our digital age. His story is not just about money and power — it’s about vision, risk-taking, and relentless belief in his ideas.
He created a platform that changed how people connect. He survived scandals that could have destroyed any other company. He took bold steps toward the future, even when billions were on the line.
Some see him as a genius. Others see him as a threat. But no one can deny that Mark Zuckerberg has shaped the online world we live in today.
Whether Meta succeeds in building the next big thing or not, one thing is certain — Mark Zuckerberg is not done yet.
