New forms of media are gaining the trust of consumers by connecting with them on a deeper level. There are many different possibilities related to social networks and the beginning of faster implementation of new social initiatives. Companies that use social media marketing are becoming more sophisticated. Global companies have recognized social media marketing as potential marketing platforms that enable their advertising campaign. Social networks are now in trend. And for companies, it represents a marketing opportunity that goes beyond the traditional company-customer relationship. The paper presents the company Tele 2, which follows modern trends and uses social networks for the purposes of advertising and communication with its existing and future users. The seriousness of social networks is best illustrated by the fact that the company Tele 2 employs a social network coordinator, a person who is in charge exclusively of social networks. An anonymous survey was conducted as part of the paper.
