Internet and Social Media have changed the lives of millions of people. The transition from Web 1.0 to Web 2.0, was characterized by the emergence of applications aimed at sharing contents on the net. In the last years of 1990 the first contents-
The colsing of Napster was followed by a great disappointment by the world's Internet users, who already showed interest and appreciation on the online content sharing.
In addition to programs for the peer-
Later in 2003, the nineteen year old Mark Zuckerberg launched a program called Facemash while attending college at Harvard. It was an experiment that led to a 450 members subscription and more than 22,000 photos displayed already the first 4 hours of program service on the network. On the basis of this experiment, a year later went into service one of the applications that has in fact changed the lives of a billion people on the planet: Facebook.
Facebook is a revolution in the way we conduct our daily activities with those around us and with those who are thousands of miles away from us. With it we discover every day new people, share moments of our daily lives, memories, feelings, opinions and emotions, as well as commenting about the news of the day or a world-
It is estimated that 140,3 Billions are the total number of connections of friendship on Facebook. An impressive number, but it marks an important fact: 140.3 fiendships per Facebook user is a number that is close to that of R.Dunbar (estimated between 148 and 150), which represents the proportion of stable relationships that our brain can manage at the same time. Translated into plain English, this means that the online social experience of Facebook is comparable to a real social experience, with users that behave as in real life when it comes to establishing relationships or contacting friends.
During the first decade of the 2000s we witness the appearance of other important applications of social media, not secondary to Facebook for their importance or penetration among Internet users.
In 2002, the Ludicorp, Canadian development company, developed an idea based on a image sharing program called Flickr. Subsequently, in 2005, Flickr was acquired by Yahoo! and its server are transferred from Canada to the United States. Although conceptually similar to other social media because of the sharing of material (mainly photography and video), Flickr was initially born as a space where to place your mages before being posted on blogs and other sites. Subsequently, the community has evolved as a virtual community with its own structure of thematic groups and forums, counting 51 million users to date.
Also in 2005, makes its appearance another application destined to leave its mark as "giant" the web: YouTube.
The first video uploaded to YouTube had a duration of 19 seconds and is owned by Chad Hurley, founder and CEO of the company, as well as the first registered user on the network. YouTube is an application that uses Adobe Flash Video technology to play back video content shared by users. With its growth, YouTube has become one of the pillars of social media currently on the web, with a traffic of users equal to 490 million monthly unique users and 92 billion monthly contacts. Mind-
Reference has been made to another important application of social media: Twitter.
Twitter is the brainchild of Jack Dorsey of a service that would allow an individual to communicate with a small number of people through text messages. In fact, in its structure, Twitter reflects very much the idea of text messaging used by mobile phones, sms precisely, with text strings of up to 140 characters sent in the form of Twitts. Given the nature of his messages short and simple, you do not define a Twitter client as a traditional type of social media (such as Facebook, for instance), but is classified as microblogging, where the conversations take place in real time and can be broken down by gategories or groups. Unlike Facebook and other social media, Twitter creates a connection between followers (users who follow the post to other users or groups) and Followed (users who are followed). If we decide to follow a user, this receives the tweets that appear between your notifications in reverse chronological order. This also includes multimedia content such as photos or links to video (read above -
Not all social networks are born for social-
We close this brief overview on major social networks pointing out one of the youngest: Google+.
The network began in 2001, presenting important new features compared to the other older and famous. For example, the sharing of multimedia content more interactive through Hangouts where users can follow comments exchanging multimedia content in real time to chat with webcam with audio-
The contacts are arranged in circles (circlets), which in turn are categorized and with different access to content or to personal data, thus enabling a higher level of privacy than in other social networks. Another highlight are the ideas (sparks) where the user can simply generate feeds directly into a box by inserting the subject of his interest, generating automatically a stream of content that will be shared by his contacts.
Despite its young age, Google said in December 2012 it reached 500 million registered users, of which 135 Mllion are active users.
Over time, a list of social networks has lengthened with the presence of other successful apps: Instagram, Pinterest, Tagged, Badoo, My Life and many others. All with their own unique features, as well as with their dedicated consumers -
