Are You What You Tweet? The Impact of Sentiment on Digital News Consumption and Social Media Sharing

초록

Although social media has helped online newspapers by allowing users to organically share articles, some have argued that it has cannibalized and hurt newspapers through reduced readership and diminished agenda-setting power. Motivated by these two opposing effects, it is critical to understand what affects the duality between sharing news articles on social media and reading the articles on news websites. Using rich click stream data on online news readership obtained from an English-language newspaper in an Asian country and social media data collected from Twitter, we focus on article sentiment as a key news content attribute and find a differential effect of sentiment on readership and sharing behaviors across the news site and third-party social media platform. Our results show that people are likely to read news articles with negative sentiment on the news site, but they tend to share articles with positive sentiment on Twitter. Specifically, a one-unit increase in content sentiment is associated with a 10.86% or 273-unit decrease in news site page views but a 17.0% or 2.10-unit increase in Twitter sharing volume. Upon decomposition of news article sentiment, we also find a contrasting positive author sentiment effect and a negative news topic valence effect on news readership. To uncover the underlying mechanism of the findings, we test the key intuitions from prior self presentation literature. We find that an increase in a Twitter user's followers (i.e., audience size) leads to an increase in the Twitter user's propensity to share positive-sentiment news articles. Our findings on the role of sentiment on content consumption and sharing affirm the coopetitive but complementary relationship between news websites and social media platforms. Our results also guide publishers to better craft their news content and manage social media presence to improve audience engagement and readership outcomes while preserving the agenda-setting ability of news media.
