WASHINGTON -- Facebook celebrates a big birthday Tuesday, marking a decade since Mark Zuckerberg launched the social media network from his Harvard dorm room.
Zuckerberg spoke with TODAY to mark the occasion and discussed how his creation has developed over the last 10 years.
"I've spent a lot of late nights pacing around my living room with teammates just trying to plot out what our next move can be in order to keep pushing forward on this mission," 29-year-old Zuckerberg said to TODAY's Savannah Guthrie.
"But one of the big things that I've taken away from the last 10 years is, there's always a next move and you just need to keep on pushing forward and keep on doing the best thing that you can."
Harvard dropout Zuckerberg is the world's youngest billionaire as a result of Facebook, which exceeded the one billion-user mark in 2012.
Understanding how people use Facebook fuels its development, Zuckerberg said.
"We pay attention to every demographic in every country, so we're going to focus on building things that teens are going to like, and we're also going to focus on building things that other folks are going to like," he said to TODAY.
Zuckerberg marked the milestone with a Facebook post, of course, saying the site was first developed because "we just cared more about connecting the world than anyone else. And we still do today."
