Facebook Turns 10, Offers Users a 'Look Back' Video showcases highlights of your time with the social network By Matt Cantor, Newser User Posted Feb 4, 2014 8:04 AM CST 3 comments Comments This Tuesday, July 16, 2013 file photo shows a sign at Facebook's headquarters in Menlo Park, Calif. (AP Photo/Ben Margot, File) (Newser) – In Internet terms, Facebook is already ancient. Today, the social network marks its 10th anniversary, and it's inviting hundreds of millions of users to share in the fun via "Look Back" videos. The project, overseen by multiple teams within the company, shows about 15 of your "most-liked" posts over music, the Verge reports. They began appearing this morning. "One of the things that motivated us was that there's really only a handful of companies that could take on something like this—that could render videos for as many people as we can," says the project's head. Mark Zuckerberg also offers a note to users: "It's rare to be able to touch so many people's lives, and I try to remind myself to make the most of every day and have the biggest impact I can," he writes. "It's been amazing to see how all of you have used our tools to build a real community." He also addresses the future: "Today, social networks are mostly about sharing moments. In the next decade, they'll also help you answer questions and solve complex problems." Feeling nostalgic?
