Who is Mark Zuckerberg?
Mark Elliot Zuckerberg briefly attended Harvard College before dropping out after Facebook took off. With roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, he launched TheFacebook in February 2004. The product scaled from campuses to the world; by 2010 Facebook had more than half a billion users and Zuckerberg was Time Person of the Year.
He took Facebook public in May 2012 while retaining voting control. Major acquisitions — Instagram (2012) and WhatsApp (2014) — cemented Meta’s grip on social attention. The 2021 rebrand to Meta telegraphed a bet on VR/AR; by the mid-2020s the company had re-centered messaging around AI (Llama models, AI assistants) while Reality Labs continued as a long-horizon R&D bet. Zuckerberg and Chan pledged in 2015 to give away 99% of their Meta shares over their lifetimes via the Chan Zuckerberg Initiative.
