Social networking brings people together into communities online where they can communicate and share their interests and opinions with others who are interested in hearing what they have to say. Communities of internet users group together on many well-known social networking sites connected.

This technology takes the fear out of having to meet new friends and acquaintances face to face and provides a more comfortable atmosphere for discussions. Social networking also allows those who have limited connection with others a way to feel involved with the world. This must be one of the main reasons millions are signed up and using these services each day.

The technology behind social networking is to ensure each person is equipped with the individual options they prefer to have a positive online experience within one of these communities. Such individual options include messaging, text chat, voice chat, blogging, email, video, file sharing capabilities, and groups for open discussions.

Each user creates a profile determining whether they are going to be categorized as internal social networking (public community) or external social networking (private community) participants. Users can also choose to communicate with only those individuals who are in their area creating a smaller circle if and when they choose to meet face to face.

Each one of the social networking websites or communities has their own form of categorization. It may be they choose to offer services to those looking for old classmates. Others offer users the ability to upload and watch video clips. The communities of users are the resources that bring new and updated content to others as they add, delete, or upload new material so there is little these websites can charge for under the circumstances.

Since these communities are free, they need some way to stay afloat. This is where business advertising comes in. Companies are charged to advertise their products and services for a fee. In turn, the money is used to maintain the site, add upgrades to the software, and keep everything running smoothly. Businesses advertising on these social networking websites have an advantage as millions of people are viewing their ads each day.
