Facebook is an online social networking website that can be accessed through any gadget that provides internet connection. You can make a Facebook account free of charge if you are 13 years of age or older. Once a user signs up, they can create a profile that provides a picture of them as their "profile picture" and information of their interest, occupations of the present and past and other topics that could help them find friends with similar answers. They may set their account up as private or public. If their account is private those who are not friends with them can not see anything on their page that they don't allow the public to see. Once they have made friends they can begin to post pictures, comments, blogs, and share others' posts. They may also choose who is allowed to see each item they post. Facebook is used by billions of people all over the world. It also shows Facebook users advertisements that are published by marketers and advertisers to create business for their companies.
Facebook was created in February 2004 by Mark Zuckerberg. He originally named it "The Facebook" that was later switched in August of 2005 to "Facebook". At the time of the creation of the social networking website, it was meant to be used by only Harvard University students and began to spread to other universities before opening access to everyone. By September of 2006 it became an internationally used website.
Through advertising Facebook allows over 1.3 billion users to access the social networking website for free. Through your interests, advertisements are posted on your feeds to draw your attention. Advertising in 2014 made up $11.5 billion out of the $12.6 billion gained to the company. The advertising is a key factor that plays in the money making for Facebook. Advertisers find this a perfect way to gain public knowledge.
