The aim of this paper is to contribute to the existing pedagogical knowledge about socialization of high school students by investigating the construct of friendship shaped exactly by the influence of social networks. Social networks that offered young people some new opportunities and options, which are in turn rapidly becoming an integral part of their lives, will be presented with the ultimate goal of having a better understanding of this new concept of friendships. The theoretical part of the work consists of five units. The first part briefly presents a historical review of friendship, the second part presents the notion of friendship and in the third part emphasis is placed on the importance of friendship to children and young people. There is also a theoretical view of the role of social networks in creating and developing friendly relationships and a view of categorizing friends on social networks. This research used interview, one of the qualitative research methods, as a method of acquiring data with the instrument being half structured interview protocol made for the purposes of this paper. The participants were the thirteen third and final year high school students which were chosen because adolescents are highly affected by socialization which is taking place by the means of social communication or new media. Phenomenological approach was used during the analysis. This research puts emphasis on which ways and to which extent does the innovative media influences the notion of friendship among adolescents. When it comes to understanding youth friendships, the results of research have shown that it is still noticed that research participants traditionally define friendship as a relationship in which the closeness, availability and trust between two people is important, and it relies on an interaction that mainly involves "face to face" communication. Nevertheless, the results show an unconsciously associative link between the concept of friendship and the concept of friendship on social networks and their interrelationships. There is also a redefinition of the term "friend", which has added some new features and roles due to the extension of the term. From the aforementioned claims and other research results, it can be concluded about the challenges that are now put to friendship and the need for further exploration of the area.
