Mark Zuckerberg

From Grokipedia

Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and entrepreneur who co-founded the social networking service Facebook on February 4, 2004, while a student at Harvard University, and serves as chairman and chief executive officer of its parent company, Meta Platforms, Inc..

Under Zuckerberg's leadership, Meta expanded from a college directory into a global platform with billions of monthly active users, acquiring Instagram in 2012 and WhatsApp in 2014, and reorienting toward virtual reality and artificial intelligence initiatives following the 2021 corporate rebrand.

His ownership stake in Meta has made him one of the world's wealthiest individuals, with an estimated net worth of approximately $245.4 billion as of February 2026.

Zuckerberg and his wife, Priscilla Chan, established the Chan Zuckerberg Initiative in 2015, pledging 99 percent of their Facebook shares to fund efforts in biomedical research, education reform, and criminal justice.

The company has encountered significant controversies, including the 2018 Cambridge Analytica data misuse incident that exposed vulnerabilities in user privacy protections and prompted regulatory scrutiny worldwide.

In brief

Mark Zuckerberg wrote a college directory that refused to stay on campus. With roommates he turned Facebook into the social layer of the internet and then into a public company he still controls.

The second act is Meta: Instagram, WhatsApp, and a stubborn investment in virtual space. Love the product or fear it — the scale is a Jewish kid from the suburbs rewriting how a few billion people say hello.
