ABSTRACT
Who sets the media agenda? is a particularly vital question in agenda-setting studies, argues Maxwell McCombs (2014). He points to three key elements: major and powerful sources, other news organisations, and journalistic norms. We address the question of how social media, in this case Twitter, contribute to media agenda-building and agenda-setting by looking at how tweets are sourced in election campaign coverage in three different countries: Australia, Norway, and Sweden.
