2 Social networks Definition History Problema Mobile social networks

3 Recently, it is this type of site that has become very popular both in the West and in Russia and Ukraine. Investments in similar projects reach hundreds of millions and even billions of dollars. In Ukraine, these amounts have passed for several million dollars and continue to grow, which indicates the growing popularity and confidence of investors, not just in the return of their investments, but also in their multiplying. The results of numerous studies indicate that over half of all Internet users have already been reached by social networks. In Russia and Ukraine this indicator is still less than the world one, but it is growing rapidly.

4 social network - a social structure consisting of a group of nodes, which are social objects (people or organizations), and links between them.

5 The term "Social Network" was introduced long before the advent of the Internet and the actual modern Internet networks, back in 1954 a sociologist from the "Manchester School" James Barnes. Modern concept in a simple form means a certain circle of familiar people, where there is a person himself - the center of the social network, his acquaintances - the branches of this social network and the relationship between these people - connections. If you look at the social network more deeply, you can find that the links are divided into types: one-sided and two-sided; networks of friends, colleagues, classmates, classmates, etc.

6 In the world, the main problem for new non-unique projects remains attracting users. The competition is very high, and almost all users who are interested in this topic have already attracted existing networks. For current social networks, the main problems are technologicalization and possible migration of users from one social network to another (such problem, in particular, is experienced by the most popular social network MySpace: more than 220 million registered users who start migrating to FaceBook and other more convenient networks). Another, special, problem is personal data, now it is widely discussed in the Western media

7 Currently, mobile tools for interaction with Internet networks are actively developing. So, mobile versions in the end of 2007 were opened at once by two giants of runet: Odnoklassniki.ru (wap.odnoklassniki.ru) and MoiMir (wap.my.mail.ru) from Mail.ru. There is also a mobile version of the social network VKontakte (wap.vkontakte.ru), and in February 2008 a mobile version appeared in the professional community E-xecutive (e- xe.mobi). On the turn, smaller social networks. Western analogues have mobile versions for a long time. Currently, one of the latest is being tested - a mobile version of the professional social network LinkedIn, which is understandable, tk. professional networks have fewer users of mobile services.
