Traditional and social media interplay in setting media agenda. Inter-medial agenda is still in the nascent state and is one of the most dynamic and uncontrolled phenomenon on the border between professional, staff-produced media and the mostly grassroots, user-generated content of social media. One of the crucial roles in the process of media agenda setting and inter-media agenda setting is played by key TV news producers and popular anchors. Our goal in this paper was to study the range of use of social media by top Polish television journalists in their everyday work. Furthermore, we wanted to get a bigger picture of how social media’s use of key TV anchors and editors influence their gate keeping and frame the content they produce. Our research was placed within the paradigm of agenda-setting theory and was conducted in the first half of 2015 with the use of a questionnaire dedicated to the selected group of top Polish mainstream TV journalists.
