Study: Brands Thrive Next to Creative AI Content
A new survey by OM Media Trials (Omnicom Media) and Zefr of nearly 5,000 U.S. and Canadian respondents examined consumer reactions to ads shown after eight types of AI-generated video. Results show mixed outcomes: ads placed next to AI-generated satire, youth depictions, or artistic content produced positive brand perceptions (refreshing/innovative), while ads adjacent to AI spam or misinformation — especially about public figures — provoked negative responses. The study found 32% of people sometimes misattribute human-created content as AI, and 41% reported improved brand opinion when AI-created content was clearly labeled. The article cites examples of problematic AI-created ads (Valentino, McDonald’s) and cites a Gartner projection that 90% of internet content could be AI-created by 2030. The authors emphasize disclosure and contextual alignment as ways for brands to manage risk.
DoubleVerify Data: AI Slop Hits 500M+ Impressions in First Half of 2026
DoubleVerify (DV) detected more than half a billion impressions of low-quality AI-generated content ('AI slop') during the first half of 2026. The data, part of DV's Global Insights report, highlights the scale and variety of AI slop across the internet, with top categories in EMEA including travel, technology, violence, sports, and vehicle disasters. Nearly half of UK consumers (48%) say seeing a brand alongside low-quality AI-generated content would negatively impact their perception. DV also uncovered a network of over 200 AI slop domains where AI prompts were left in the site code. The findings underscore the need for advertisers to identify and avoid such content to protect brand safety and reduce the financial incentive for its creation.
Gartner: AI Erodes Trust in Influencers and Brands
A Gartner survey of 1,006 US consumers reveals that the growing prevalence of AI-generated content is eroding trust in influencers and brand communications. 35% of respondents say they rely on influencers less often due to AI content. 65% believe companies use too much AI-generated content in marketing, and 57% say this has reduced their trust in brand messages. Gartner describes the flood of low-quality AI content as 'AI slop'. However, 43% of consumers say they now turn more to real people for purchase recommendations. The study highlights a growing need for transparency and expertise in marketing as consumers increasingly question the credibility of AI-generated content.
