Going beyond source and content pluralism, we propose a two-dimensional audiencebased
measure of perceived pluralism by exploiting the practice of \u201csocial TV\u201d. For
this purpose, 135,228 tweets related to 30 episodes of prime time political talk shows
broadcast in Italy in 2014 have been analyzed through supervised sentiment analysis.
The findings suggest that the two main TV networks compete by addressing generalist
audiences. The public television offers a plural set of talk shows but ignores the antipolitical
audience. The ideological background of the anchorman shapes the audience\u2019s
perception, while the gender of the guests does not seem to matter
