Mark Zuckerberg

Facebook, the social network Zuckerberg runs, has been an information hub during the pandemic, but has come under scrutiny for spreading vaccine misinformation.

In June 2021, a judge dismissed antitrust cases brought by states and the federal government, which could have forced Facebook to sell off Instagram and WhatsApp.

Zuckerberg started Facebook at Harvard in 2004 at the age of 19 for students to match names with photos of classmates.

He took Facebook public in May 2012; he now owns about 12% of the company's stock.

In December 2015, Zuckerberg and his wife, Priscilla Chan, pledged to give away 99% of their Facebook stake over their lifetimes.
