The goal of Facebook was to have a way that makes communication between people in the world faster and easier, so that they can share information with each other and get to know each other more.

So how can one online service, which has undergone many changes, remain so successful :

1. Facebook is easy to use:
  Facebook is the easiest way to use the website, and even a young 14-year-old can easily understand all the features that are included in the website.  One can write, or comment, like others' posts with just a click of the mouse.  Therefore, this is the most prominent reason for the site's gaining international fame

2. Better interface:
  The design and look of the website is also very attractive which gives the user a more superior interface to work on.  One can easily find his friends, follow celebrities, message and chat or with the new feature even call a friend.  All these power packed features that are equipped in such a light location make it more useful than its competitors.

3. Entertainment:
  The website now allows people to play games, use interesting apps and watch videos which makes it an entertainment provider.  Other than this, a person can join a group and start a conversation with strangers and make new friends

4. Find old friends:
  Also, one of the main reasons why the site is accepted is that as the site's network grows exponentially, we can connect and chat with our old friends from school and college.  We just have to know the name of the person concerned and through the Facebook search engine we can find it easily.

5. Security at the highest level:
  The email and password with which we open our accounts are secured with a very high level of security so it becomes almost impossible for hackers to open an account that they do not have.  A notification is also sent if someone tries to open the account from a location other than the user.  So users know that their data is safe and secured.

6. A site that does not sleep:
 Facebook is a global site that never sleeps. There is constant activity, day and night, and is renewed around the clock. Any time you look, you find new friends, whether in the morning, in the evening, or in the middle of the night.. The reason is of course that Facebook is a multilingual global site with a variety of friends.  Participants come from multiple countries and geographical locations covering all continents of the globe.

The continued success of Facebook is not to stop providing more services to users, as they have added to the site the video chat feature and the commenting feature with pictures, which are among the characteristics that fascinate users and link them more to Facebook.
