Facebook has designated Feb. 4, 2016 as "Friends Day" in celebration of the social networking site's 12th birthday. It's calling attention to how the site has connected people all over the world, with a Friends Day video montage appearing on user News Feeds, displaying photos of some memorable moments with friends and family.
Given Facebook's massive reach, it's easy to forget the site's humble Harvard University dorm room beginnings. The earliest incarnation of the site was Facesmash, which was launched October 28, 2003 by Mark Zuckerberg and Harvard classmates Andrew McCollum, Dustin Moskovitz, and Chris Hughes. That early site was designed as something of a "hot or not" game comparing pictures of different undergrads based on their attractiveness.
That earlier website laid the groundwork for Thefacebook.com, which launched on Feb. 4, 2004. Originally just open to Harvard students, the site soon expanded to Columbia, Yale, and Stanford, then the rest of the Ivy League and Boston-area schools, before spreading across the country and around the world.
Over the next decade, what started as a private website for college students became something that everyone from tweens to grandmothers were using. Facebook has grown by acquiring the likes of WhatsApp and Instagram, adding features that broaden the company's reach and appeal.
