Innovation always arrives with the confidence of inevitability. Advertising embraced every wave, convinced that more data, better targeting and new tools would sharpen persuasion and elevate the craft. Instead, something stranger happened. The technology advanced. The imagination retreated. With every breakthrough, the work felt a little smaller.

For two decades, the industry treated innovation as progress. Programmatic promised efficiency. Personalisation promised relevance. Social platforms promised connection. AI now promises creativity at scale. Yet each leap brought an unintended consequence: the slow erosion of the qualities that once made persuasion work at all. Automation delivered reach but drained attention. Personalisation increased precision but produced uniformity. Infinite content created abundance but flattened originality.

The turning point came when advertising stopped paying for attention and started paying for access. Once platforms controlled distribution, the purpose of advertising shifted. Its job was no longer to persuade a human being. Its job was to feed a machine.

In that moment, creativity ceased to be a competitive advantage and became a variable in an optimisation loop. Innovation didn’t accelerate originality. It standardised it. In a system calibrated for predictable performance, surprise becomes a liability and replication becomes the path of least resistance.

Economic incentives deepened the problem. Platforms captured distribution, data and value. Agencies adapted by serving the metrics that platforms dictated. Clients, pressured by volatility, demanded certainty and measurable outcomes. Creativity became something to justify rather than something to pursue. The work bent itself around what could be tracked, not what could be felt. The industry once prized ideas that lived in culture. It now mass-produces content that survives in a feed.

Behaviourally, the consequences are severe. Humans respond to tension, novelty and the unexpected. Algorithms reward what has performed before. When a system selects for the familiar, it punishes the original. Advertising shifted from making meaning to manufacturing micro-interactions that register as activity but rarely accumulate as persuasion. The ambition of the work shrank to match the duration of a swipe.

Culturally, infinite content did not expand possibility. It converged it. Templates spread faster than ideas. Trends collapsed into hours. Brands that once shaped culture now orbit the same reference points, moving in sync with the same logic of the platforms they depend on. In a landscape where anything can be produced instantly, almost nothing feels crafted.

AI arrives as the next accelerant. It offers astonishing ease but amplifies the worst instincts of the existing system: speed over substance, scale over intention and optimisation over imagination. If deployed within the same incentive architecture, it will not revive the craft. It will accelerate its dissolution. The industry will not drown in bad ideas. It will drown in endless competent ones.

The uncomfortable truth is that advertising did not decline because innovation failed. It declined because innovation succeeded in a system that rewarded efficiency, predictability and standardisation. It became frictionless. It became measurable. It became scalable. But persuasion has never been any of those things. Persuasion is human, slow, emotional and fundamentally resistant to automation. When everything becomes efficient, nothing feels meaningful.

Advertising used to be a cultural force. It did not have to lose its soul. It simply entered an economy designed to value access over attention, repetition over originality and metrics over meaning.

Once the platforms became the intermediaries, the outcome was not just predictable but unavoidable. Justifying it was easy: the audience had moved, and the click-through rates looked reassuring. But numbers can rise even as the work diminishes.

It is a bleak irony that one of the world’s most inventive creative industries lost so much of its creative inventiveness in the name of progress
