Facebook:

• Facebook's vision statement is “People use Facebook to stay connected with friends and family, to discover what's going on in the world, and to share and express what matters to them.” Its focus is on the influence the company has in the social media sector. Give people the power to build community and bring the world closer together.

• Facebook was founded in 2004. It has grown into a global phenomenon, counting more than 750 million users, including approximately 70 percent from outside of the United States. The social networking site was started with a much more modest purpose. Founder Mark Zuckerberg developed Facebook while he was a student at Harvard University initially as just a social networking site for the university's students.

• Facebook's stated mission is "to give people the power to share and make the world more open and connected." On its site, Facebook explains that it believes that increased connection between people through their site will lead to better understanding between disparate groups. Facebook is designed to be free for its users; it should give them control of their information and who can access it, according to the company's statement of principles.

• While many argue that social media networks only distract employees, the opposite may be true. When employees take brecks to do something that interests them, they tend to be happier and more productive. If employees enjoy a quick break to check the Facebook News Feed and feel more connected to friends and family, they may be more relaxed and focused when they get back to work.
