This study examines how social media and traditional media shape public discourse during sociopolitical issues. The researchers analyzed media coverage and online discourse around the Stop Online Piracy Act (SOPA) to test propositions about how different types of media may afford emancipation through participation or hegemony through control of discourse. The findings showed that social media allowed more participation through unconstrained authorship and influence, but also exhibited more constrained framing of issues than traditional media. Lean social media further exacerbated these effects by limiting participation and framing. Overall, both social and traditional media were found to both enable emancipation through participation and exhibit hegemonic control of discourse framing.
