Meta CEO Mark Zuckerberg, who co-founded Facebook in 2004 with Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes, shared a video on Instagram to mark the platform's 20-year anniversary. "20 years ago, I launched a thing. Along the way, lots of amazing people joined and we built some more awesome things," Zuckerberg wrote. "We're still at it," he added.
