The practice of live tweeting while following a television programme is quickly becoming a widespread phenomenon. However, in Italy, commenting on a political debate via social media is a novelty. This article presents the first exemplary case study in an Italian context, the ‘Italia bene comune’ debate, hosted by SkyTg24 on 12 November 2012. This debate focused on elections to designate a candidate to lead the government from the centre-left coalition. The findings indicate the new hybridisation of media: television’s centrality is confirmed regarding its domination in the public space in which political discussion occurs, and the web demonstrates its own capacity for an active role in an event central to Italian politics. The new element was the active participation of a vocal minority who commented online as the media event unfolded live on television.
