The new Chief Marketing Officer of America’s biggest brands doesn’t sit in Madison Avenue boardrooms. It sits in Washington. And it doesn’t care about brand love, market share, or cultural relevance. It cares about tariffs.

This summer, General Motors reported a $1.1 billion tariff hit. Apple lost another $1.1 billion in a single quarter. Nike: $1 billion. Adidas: $218 million. These weren’t bad campaigns. They weren’t consumer revolts. They were politicians pulling levers that bled global brands dry.

And the bleeding has reached advertising.

The Ad Industry’s Sudden Survival Mode

The Interactive Advertising Bureau has slashed its 2025 forecast: US ad spend growth down to +5.7%, from +7.3% in January. The first half of the year looked stable. The second half is where the pain lands.

Marketers aren’t pretending otherwise. Nearly half say they’re cutting budgets outright. Others are shortening campaigns, pausing buys, or fleeing to performance-driven channels where every click can be measured.

The casualties over at the USA are obvious:

• Linear TV spend: -14.4%.
• Print, radio, OOH: -12.7%.
• Meanwhile, social (+14.3%) and CTV (+11.4%) are the lifeboats.

It’s a forced pivot from storytelling to transaction. As one media buyer put it bluntly: “Forget brand equity. Just sell before the next tariff drops.”

Tariffs Don’t Just Tax Goods …They Tax Culture

For decades, marketers told us they were culture’s architects. They built myths, symbols, slogans. But if trade policy can erase billions in ad spend overnight, then culture isn’t designed in creative studios anymore. It’s dictated in tariff negotiations.

That Nike campaign about human potential? It now competes with headlines about price hikes. Apple’s latest innovation launch? Drowned out by quarterly earnings wrecked by tariffs.

Marketers don’t control the message when they’re busy firefighting margin losses. Politicians do.

The Quiet Extinction of Branding

This isn’t just a budget story. It’s the slow death of brand advertising itself.

With customer acquisition and repeat sales now the only goals that matter, campaigns have collapsed into endless “buy now” loops. The promise of brand-building has been traded for measurable clicks.

It’s not strategy. It’s survival. And survival stories don’t go viral. They go silent.

Who Really Runs Advertising Now?

The ad industry is bracing for more shocks in 2026. Social, CTV, and retail media will grow. Traditional media will shrink further. Marketers will keep demanding proof of ROI at every step.

But the bigger story is this: advertising has lost sovereignty. It no longer writes culture on its own terms. It rents its megaphone from politics.

In 2025, the Chief Marketing Officer of American brands isn’t a strategist, a creative, or even an algorithm.

It’s the tariff.
