Round-trip agenda setting: Tracking the intermedia process over time in the ice bucket challenge

Despite the social media's agenda-setting power, the literature provides little understanding of how social media agendas survive and last long enough to trigger substantial public discussions. This study investigates this issue by tracking the ice bucket challenge campaign over an 18-week period. This article claims that the pattern of the intermedia process evolves over time along with the issue-attention cycle. We observed a round-trip intermedia agenda setting where the direction is reversed as the agenda waxes and wanes. Both social and mainstream media continued to generate a heightened level of issue attention after the buzz was cooled down.
