Today, social media has become the number one news source; therefore, citizen journalists, news agencies, politicians, and various professionals often share news on their social media accounts, which changed journalism's face. Many advantageous features previously associated with internet journalism can be found on social media nowadays. With the inherent connectivity of social platforms, social media journalism started to be debated as a concept. Thus, news agencies enrolled in social media measurement sites to track their performance and started to share daily news on their social media accounts, which heralded a new era of journalism and new ways of operating. New types of social media journalism such as Twitter journalism, Instagram journalism, YouTube journalism, and more specifically, Story journalism meets the needs of the online social media society for information and create new venues that are predicted to expand soon. This study aims to investigate three news agencies which are known for their popularity in Turkey, in terms of social media journalism. In the research carried out according to the general survey model, the number of followers on Facebook, Instagram, Twitter and YouTube accounts, news sharing frequency, weekly follower growth rates, and the types of shared messages of three news agencies were examined and compared in terms of social media journalism. Thus, it is believed that news agencies' attitudes towards the new journalism approach will guide future studies.
