Mark Elliot Zuckerberg (born 14 May 1984) is an American internet entrepreneur and philanthropist. He is the co-founder, chairman, and CEO of Meta Platforms (formerly Facebook, Inc.). He launched Facebook in 2004 from his Harvard dormitory room, and it rapidly grew to become the world's largest social network, connecting billions of people. Zuckerberg has overseen the company's acquisitions of Instagram, WhatsApp, and Oculus, consolidating its dominance in social media. In 2021, he rebranded the company to Meta to pivot towards the "Metaverse." His leadership has been defined by rapid innovation but also intense scrutiny over user privacy, data handling, and the platform's role in political discourse.
