This year, artificial intelligence made a bold entrance into the world of advertising — but not without controversy. As major brands rushed to integrate AI into their marketing strategies, several high-profile campaigns sparked public backlash, raising concerns about authenticity, ethics, and the future of human creatives. One of the most talked-about missteps came from McDonald’s Netherlands, which released an AI-generated holiday ad titled “The Most Terrible Time of the Year.” The satirical 45-second spot featured chaotic holiday scenes like kitchen disasters, ice rink injuries, and a stuck Santa sleigh, with the brand positioning its restaurants as a safe haven. But viewers found the tone cynical and the characters unsettling, with some calling the ad “creepy.” After a wave of negative reactions and disabled comments, McDonald’s removed the ad entirely. The company later stated it respected the holiday spirit for many and remained committed to delivering “Good Times and Good Food.” Coca-Cola’s 2025 holiday campaign also faced criticism, despite its use of AI. The brand released three AI-generated versions of its classic “Holidays are Coming” ad. One version drew attention for inconsistent visuals — particularly the number of wheels on the holiday trucks, which appeared to change mid-roll. While the ad received high scores in pre-testing from companies like System1 and DAIVID, critics pointed to the technical flaws as evidence of AI’s current limitations. The ad’s creative team defended the work, saying Coca-Cola is pushing the boundaries of what’s possible in AI-driven storytelling. Meta’s ad platform also made headlines when it automatically replaced a high-performing ad for apparel brand True Classic with an AI-generated image of an elderly woman in an armchair. The ad, meant to feature a relatable millennial man, was altered without the advertiser’s full consent, due to default settings in Meta’s Advantage+ AI tools. Advertisers reported that the auto-generate feature was turned on by default, even when they had disabled it. Meta said users can review AI-generated content before running ads, but the incident highlighted growing concerns about transparency and control. H&M’s plan to create digital twins of 30 real models stirred controversy in the fashion world. The fast-fashion giant announced it would use generative AI to produce virtual models for social media and ads, with the real models retaining rights to their digital versions. While H&M said the initiative was meant to support creatives, critics like fashion influencer Morgan Riddle called it “shameful,” and Model Alliance founder Sara Ziff raised alarms about worker displacement and lack of fair compensation. H&M acknowledged the concerns, stating it is still learning how to use AI responsibly. Vogue’s August 2025 issue added to the debate when it featured an ad for Guess with AI-generated models named “Vivienne” and “Anastasia.” A small disclaimer noted the models were created by London-based agency Seraphinne Vallora. The ad drew sharp criticism online, with readers accusing the brand of promoting unrealistic beauty standards and threatening real jobs. The agency’s founders insisted the goal was to complement, not replace, human creatives, but the backlash underscored a growing unease. These incidents reflect a broader shift: while AI offers efficiency and innovation, it also risks alienating audiences when it feels inauthentic or exploitative. A November survey by Tracksuit found that only 18% of U.S. consumers viewed AI-generated ads positively, with 39% expressing negative sentiment. As a result, some brands are pulling back — influencer campaign data shows a 30% drop in AI social account partnerships in the first eight months of 2025. The message is clear: AI in advertising is here to stay, but it must be used with care, transparency, and respect for both people and creativity.
