Social networks have turned into an authentic phenomenon and every time they possess a major number of followers. To be in touch with your friends, to share with them photos and videos, to meet again with people with whom you have lost the contact, to practise microblogging or to follow your idols, there are only some of the possibilities that social networks offer to us.We know the most Most known ones like Facebook, MySpace, Twitter, Xing, LinkedIn, Tuenti and Flickr,and we also now what are they for, But do we know the origin of the social networks?

The origin of the social networks goes back 1995, when Randy Conrads creates the web site that allows  people to recover or  support the contact with old classmates of the college, institute, university, etc. In 2002 web sites appear promoting the networks of friends’ circles on line, and it became popular in 2003 by the arrival of such sites as MySpace or Xing.

Now we know where they come from,I´m going to explain how do experts organize them.

In some sites there is applied the same typology that was in use for classify portals. There are two main types:

Vertical for type of user: aimed to specific public, for example, professionals uses Linkedin.

Vertical for type of activity: those who promote a particular activity. To watch Videos you have YouTube,and to Microblogging the most used social network is Twitter.

What must offer a social network to be successful?

“The key factor in order that a network is successful is his social, cultural and idiomatic transversavility. The global osmosis is important for the success of a social network.” said Adolfo Plasencia Teacher of multimedia and Web concepts.

How does it see the future of the social networks?

” Growing vertically and proliferating from the most general to the most specific. The first ones always will be the first ones, because they throbbed first, but many of that joined them, they have been given of fall because it is not what they search or are too diffuse and “entertain” in excess or do not give “game” for fault. For it, I suppose that we will see how there will be created social on-line specialized networks by the topic of interest, since every time it is simpler to develop or to mount your own social network with software of opened and / or free code.” said Elena Benito Ruiz, teacher of the VCU and consulting elearning and of social average.
