Doctoral dissertation analyzing literature and previous research represent prior knowledge regarding marketing, e-marketing and political marketing. A specific term, respectively a kind of marketing that will be analysed, is political marketing. The term refers to the planning and realization of political party relations with the electorate and other groups within the public through the political promotion and other activities aimed at obtaining public support, parliament or elections. The fundamental determinant of modern marketing is an orientation to the market and consumers. Marketing is universal. It is applied to all business entities, regardless of their size or business. The basis of marketing knowledge consists of various theories, techniques, methods, resources, procedures and experiences. The most comprehensive definition of marketing to Philip Kotler is: "Marketing is human activity directed at satisfying needs and wants through exchange processes2". From the viewpoint of a business, marketing aims at gaining a profit, while with the view of consumers it aims to meet its needs. The consequence of globalization and technological development is e-marketing. This term demonstrates the expansion of marketing in the virtual space. It is defined as the way of achieving marketing activities of the company with intensive application of information, telecommunication and internet technology. The dissertation provides a systematic and comprehensive overview and analysis of the use of the techniques of political marketing, primarily digital political marketing, especially digital communication in the pre-election campaign in the IV. (fourth) and VIII. (eighth) constituency for the Croatian Parliament in order to determine the influence on decisionmaking on the choice of parties and candidates of a particular age-group of voters, determining what social networking role is and what age group is influenced more by the Internet media in the choice of parties and candidates. The two constituencies were chosen because of their differences, IV. as a predominantly rural electoral unit and VIII. as a predominantly urban electoral unit. The continuation of the primary research is a secondary survey of bids, respectively representation and promotion of parties and candidates in the Parliamentary Elections, which explored all political parties and candidates who participated in the political process. Secondary research is based on available Croatian and foreign literature that was used to form a scientific funnel.
