Facebooks mission is to give people the power to share, and make the world more open and connected. Through our growing family of apps and services, were building a different kind of company that helps billions of people around the world connect and share what matters most to them. Whether were creating new products or helping a small business expand its reach, people at Facebook are builders at heart. Our global teams are constantly iterating, solving problems, and working together to make the world more open and accessible. Connecting the world takes every one of us—and were just getting started.

Facebook is where people connect, and in recent years more people have been using Facebook to connect in another way: buying and selling with each other. This activity started in Facebook Groups and has grown substantially. More than 450 million people visit buy and sell groups each month — from families in a local neighborhood to collectors around the world.
