The evidence shows these formats are increasingly popular and officially promoted in Vietnam, but popularity and institutional adoption are not the same as proven effectiveness. No Vietnam-specific study in the evidence base directly compares short-form video, infographics, or podcasts against long-form text on ideological comprehension, persuasion, or retention. Meanwhile, peer-reviewed research found short videos scored lowest on content clarity versus traditional articles, and political book revenue surged 167.9% in 2025 — undermining the claim of categorical superiority.
