Mark Zuckerberg

Mark Elliot Zuckerberg had already become the world’s youngest self-made billionaire in 2007, at 23 years of age. He is a Facebook, Inc. co-founder. Mark Elliot Zuckerberg is also a co-founder of Breakthrough Starshot, a Solar Sail spaceship development project. Mark was born on May 24, 1984, in White Plains, New York, the United States.

On February 4, 2004, Mark Zuckerberg, a Harvard University graduate, started the Facebook Social Networking site. The rapid expansion of Facebook beyond colleges made Mark Zuckerberg take Facebook officially to the public after it had recorded up to one billion users in 2012.

In 2016, Mark Zuckerberg ranked 10th on Forbes of The World’s Most Powerful People. Today, he is the youngest in the top 10 richest people in America. In October, Facebook changed its name to Meta Platforms to focus on establishing a nebulously defined (and potentially undesirable) tech utopia known as the "metaverse." He has excellent cause to flee the physical world, where Meta stock has fallen by half since its peak in September. For the first time in six years, he has dropped out of the top ten richest people on the planet.
