Short-Form Video Content Dominance
Available evidence, such as continued vertical/short-form growth statistics (TikTok usage, social media ad spend growth) and even out-of-home advertising pivoting to vertical formats, supports continued dominance of short-form/mobile-first video. No articles indicate engagement stalling or brands shifting back to long-form, so the falsification criteria are not met, though direct engagement data is limited.
What would prove this wrong
Engagement or usage data show short-form video growth stalling or reversing on major platforms, or if brands broadly shift ad spend back toward long-form video over short-form.
