Mark Zuckerberg

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.

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.

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.

Mark's family used "ZuckNet" to communicate with each other in different rooms and Mark's dad's dental office, which was connected to their family home. ZuckNet ultimately didn't go anywhere, as AOL's instant messaging platform soon replaced it.

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. Since then, Zuckerberg has appeared a total of eight times to defend Meta against privacy violations, child safety, and more. (Some users may experience a paywall.)

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. (Some users may experience a paywall.)

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.

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.

Zuckerberg said many of the story arcs and plot details in "The Social Network" were inaccurate and harmful. In particular, the movie portrayed Zuckerberg's motivations for starting Facebook as a ploy to get a girlfriend, which Zuckerberg says is untrue, as he was already dating his now wife when he started Facebook. However, he did commend the movie for paying close attention to details about Zuckerberg's clothing and the layout of the Facebook office.

Open source technology is software, hardware, or code that's publicly accessible for viewing or editing. Zuckerberg has been an advocate for open source since 2003 and said he wouldn't have been able to build Facebook without open source code.
