This paper deals with the impact of social networks that have become a global phenomenon and a growing trend of communication on creating news in information programs of national televisions. The aim of this study was to consider the growing influence of releases on social networks in central information broadcasts of public and commercial televisions, to examine to what extent social networks affect their work and whether they serve as a source of relevant, primarily political messages in the central information programs of national televisions (HTV, RTL, NOVA TV). It was also sought to explore which social networks are most used, and which television lead in transmitting messages from social networks. Given the specificity of television as a visual media, the paper seeks to examine how the transmission of social releases affects changes within the television itself as media. The exploration plan encompasses the use of two empirical research methods: a quantitative research method through a written survey, and a method of analyzing the content through 306 entries in which keywords were found (Facebook, Twitter, Instagram, You Tube, social networks). Through the use of the questionnaire survey, in the second phase of the survey, 73 journalists were considered to be adequate to represent the population of journalists working in the news broadcasts of the three televisions. It is clear from the results of the research that the disclosure of information from social networks in the central informative news of public and commercial television has become imperative, and the most commonly used network is Facebook. But the hypothesis that public television uses social networks to a lesser extent than commercial television - has not been confirmed. Namely, although according to the perception of surveyed journalists of commercial television, they use social networks more widely than public television, and there is no statistically significant difference among them in the frequency of use of social networks. However, it should be noted that, during the analyzed period on commercial televisions (Nova TV - 102 TV reports, RTL today 89), there were statistically significantly more such TV reports than on the public TV station (75 reports). Other hypothesis is that journalists mostly do not check the authenticity of social media releases and sources (Facebook being the most commonly used) have been rejected or an alternative hypothesis has been confirmed according to which journalists in most cases check the authenticity of social networking and sources. However, given the journalists' claims, the questionnaire raises the question - are there any journalists who want to offer socially acceptable answers to the interviewer. Furthermore, it is found, through the third hypothesis, that social networks are used by local politicians - executive and parliamentary authorities, ie their messages from social networks are most commonly transmitted in central broadcasts of public and commercial television. The hypothesis that television as a traditional audio-visual media moves away from its nature and specificity and loses its authenticity and professionalism, the research results show, is confirmed. However, as all the above indicates that in the background of the negative relationship of individual journalists to social networks - the irresponsible way of using social networks (transferring information without further verification) and to a lesser extent the theory of abandoning television from its media nature by transmitting social network relases - the hypothesis is neither confirmed nor dismissed. Given that, as stated earlier, an accepted hypothesis is the one in which journalists in most cases check the authenticity of the sources on social networks - we can conclude that television does not lose its authenticity and professionalism by using social networks. In addition to the fact that television must keep up to date with new media trends, it is important that aside from journalism (the necessity of checking information), it also retain its specific audiovisual postulates - insisting on visual quality.
