Picture the exact red of a Coca-Cola delivery truck rolling through the snow, fairy lights strung along its sides, a whole town lighting up as it passes. You have seen this ad. You have felt this ad. The 1995 "Holidays Are Coming" commercial is lodged so deep in the collective brain that a generation cannot see a red truck in December without hearing the jingle.
Now picture the same trucks, the same snow, the same lights, except a machine made all of it, and everyone can tell. That was Coca-Cola's 2024 holiday campaign, and the internet did not send warm regards.
Two Christmases, one complaint
In November 2024, Coca-Cola remade its holiday classic using generative AI. Three studios, Secret Level, Silverside AI and Wild Card, stitched it together from four different AI models. The reaction was swift and brutal. Viewers called it "soulless" and "devoid of any actual creativity." The complaint was not that the technology looked broken. It was that the warmth was gone. You cannot fake the feeling of a thing people have loved for thirty years, and pretending you can is its own kind of insult.
Most brands would read the room and quietly retire the experiment. Coca-Cola did not. In November 2025 it came back with two more AI-generated holiday ads, this time starring anthropomorphic animals gazing lovingly at the trucks. Same trucks. Same backlash, louder. Social media reached for the same vocabulary again, plus a newer one: "digital slop." Some viewers called for boycotts. Bold strategy, running it back.
What is striking is not that one company misjudged the mood twice. It is that the audience had, in the span of a single year, developed a shared and confident vocabulary for a feeling they used to struggle to name. They did not need a media critic to explain what was wrong. They just knew.
"Slop" became a business metric
"AI slop" started as a shorthand for the low-effort garbage flooding your feeds, the six-fingered hands and the melting logos. Then it quietly graduated. By 2026 the word had stretched to cover technically competent AI work that simply feels generic, derivative or hollow. That shift matters. It means the problem is no longer a rendering glitch you can patch with a better model. The problem is that people can feel the absence of a person, and they have decided they do not like it.
The numbers turned the vibe into something a CFO has to care about. A Harris Poll picked up by Marketing Brew found consumers are exhausted by AI and trust ads less when they suspect a machine made them. Other 2026 surveys landed in the same place, with strong majorities saying AI-generated ads feel less authentic and make them less likely to trust or buy from the brand. Consumer excitement about AI has been sliding for two years while fatigue climbs. When more than half your audience reduces engagement the moment they smell a bot, "we saved on production" stops being a win.
Everyone is using it. Almost nobody admits it.
The dirty secret underneath the eye-rolling is that the same industry mocking Coca-Cola is quietly shipping plenty of AI work of its own. A 2026 look at AI in creative work found a majority of creative professionals have used AI on client jobs without disclosing it, and only a minority always own up to it. Adoption is no longer fringe either. Generative AI went from roughly half of marketing teams in 2024 to the high eighties by 2026, which is about as close to universal as these things get.
So the fight was never really pro-AI against anti-AI. Everybody is using it. The line that actually matters runs between the brands that use it invisibly, in service of something a person still shaped, and the ones that hand the machine the wheel and hope the audience will not notice. The audience noticing, over and over, in real time, with a fresh word for it, is the whole story of the last two years.
The authenticity premium is real, and it pays
Here is the twist that should make every creative sit up. The backlash did not just punish the brands leaning into AI. It started rewarding the ones loudly refusing it.
Aerie ran an anti-AI campaign in early 2026 that explicitly called out AI slop, and the "no AI" pledge tracked to a 23 percent sales lift in the prior quarter. Dove committed back in 2025 to never replacing real people with AI in its advertising. A small but growing cluster of brands now treat "made by humans" as a selling point, printed on the label like organic or fair trade. Breef has been tracking how "AI-first" brands are starting to fall flat while the human-forward ones pick up the trust nobody else wants to spend on.
None of this means AI is uninvited. It means authenticity became a position you can own, and positions that pay attract competitors fast. The agencies that understand this are not the ones asking whether to use AI. They are the ones asking where the human fingerprints should show.
The smartest brands hide the machine
Watch what the winners actually do rather than what they say, and a pattern appears. They use AI everywhere, and they never make it the headline. The strategy that keeps working in 2026 is to treat AI as infrastructure rather than innovation: use it to test more variations, personalize at scale, move faster, and then get out of the frame so the finished work still feels like it came from people who cared.
This is the quiet lesson underneath the noise. The backlash is not really against AI. It is against being able to see the AI. It is against the sensation of a brand deciding your attention was not worth a human's time. Nobody boycotts the spell-checker. They boycott the Christmas ad that told them, without meaning to, that the machine was cheaper than caring.
The creative industry itself is split down the middle on this, which is its own tell. A 2026 report on the state of AI in creative work found the people using these tools most are often the least sure they are ready, and disclosure is patchy at best. The tools raced ahead of the taste required to use them well. That gap, between what a model can generate and what an audience will accept, is the whole ballgame right now.
What this means for the people who make the work
If you make brands and creative for a living, the past two Christmases were not a warning. They were a gift, wrapped badly and left under the tree by the companies that thought your job was a cost line.
The backlash proved something creatives have argued forever and could never quite measure. Taste is not decoration. Judgment is not overhead. The thing you do that a model cannot, knowing which idea has warmth and which one has only competence, turns out to be worth 23 percent in a quarter to a lingerie brand. The market just put a number on the soul.
The move is not to swear off the technology and cosplay as a 1995 film crew. The move is to use AI for the parts that were always grunt work, the variations and the resizes and the first rough pass, and to spend the hours you save on the parts only a person can carry. Multiply's chair Lotta Malm Hallqvist has put the stakes bluntly, arguing that AI is too powerful to leave in the wrong hands, which is another way of saying the humans have to stay in the room. That is the entire bet behind Multiply: AI that amplifies a creative team instead of impersonating one.
So let Coca-Cola run the trucks back a third time. Somewhere a smaller brand is about to release something a person clearly sweated over, and the audience that just learned the word "slop" is going to know the difference in half a second. Your move is to make the thing they can feel a human made. The machines got good at looking human. Being human is still the part you own.
