Advertising trust levels hit five-year high despite generative AI risks

The recovery in consumer sentiment suggests that transparent regulation and creative quality are effectively countering ad fatigue. For streaming platforms, this data validates the shift toward premium, less intrusive ad experiences, as campaigns that prioritize brand trust demonstrate a 41% higher probability of driving customer acquisition and price premiums. As generative AI becomes a standard production tool, the industry must balance efficiency with the risk of 'ordinary' content that could trigger consumer vigilance and distrust. Watch for the Advertising Standards Authority to refine disclosure requirements for synthetic media to maintain these fragile sentiment gains.

The Advertising Association's trust research sits within a broader ecosystem of industry self-regulation and standards enforcement. In early 2025, the Advertising Standards Authority published updated guidance requiring clear labeling of AI-generated content in advertisements, marking the first time the UK regulator issued specific disclosure expectations for synthetic media used in commercial communications. That move followed a 2024 consultation where the ASA received over 2,000 responses, with consumer groups arguing that undisclosed AI imagery eroded confidence in brand claims. The ASA's intervention positions it as a key gatekeeper for the trust gains the Advertising Association now celebrates, particularly as generative AI production tools proliferate across agencies and in-house creative teams.

On the business side, the IPA has been quantifying the commercial value of trust-aligned creative strategies. The IPA Effectiveness Databank's 2025 analysis found that campaigns scoring in the top quartile for perceived authenticity delivered 2.3 times the market-share growth of those in the bottom quartile, reinforcing the economic case for the Advertising Association's emphasis on quality over volume. Meanwhile, Credos, the industry's research arm that conducts the annual trust tracker, expanded its methodology in 2025 to include sentiment measurement around AI-generated advertising specifically, reflecting growing concern that synthetic content could become a distinct trust category separate from traditional advertising formats. The Advertising Association's Matt Bourn has publicly stated that the industry must treat AI transparency as a non-negotiable baseline rather than a competitive differentiator.

Competitive pressure from adjacent sectors is also shaping how advertisers approach trust. A 2025 Edelman Trust Barometer special report found that 67% of consumers said they would stop buying from brands they believed were using AI to deceive them, a finding that has prompted several major holding companies to adopt internal AI disclosure policies ahead of any regulatory mandate. WPP and Publicis Groupe both published internal AI ethics frameworks in the first half of 2025, with Publicis requiring watermarking on all AI-generated visual assets used in client work. For streaming platforms running ad-supported tiers, these dynamics suggest that creative quality standards and transparent AI labeling are becoming table stakes for maintaining subscriber goodwill alongside advertiser relationships.
