The Junior Layer Is Gone. Who's Training the Next Generation?

Picture a twenty-three-year-old who spent three years in portfolio college. Brilliant book. Two placement interviews. Ghosted. She's not alone.

The advertising and creative services sector is in the middle of a structural rupture so total, so swift, that even the people running agencies haven't caught up with what it means. And the numbers now confirm it. AIBD analysis of Companies House data shows just 2,554 new SIC 73.11 advertising agency incorporations in Q2 2026, a collapse of 31.4% versus the prior period. New agency formation, that classic barometer of creative industry confidence, has fallen off a cliff. You can't chalk this up to interest rates.

The Floor Has Dropped Out

The macro picture is brutal enough on its own. Bureau of Labor Statistics data showed the advertising, PR and related services sector sitting at 488,600 total jobs in May 2025, a 9.9% drop from twelve months prior. That's 54,000 positions gone in a single year. Entertainment and media companies cut more than 17,000 jobs in 2025, an 18% increase on the year before, according to Challenger, Gray & Christmas.

But here's what the headline numbers miss. The cuts aren't random. They're surgical. Burkan Bur, Managing Director at The Ad Firm and a lecturer at UC San Diego, is unambiguous: "Jobs are not being killed off. They are being reduced to smaller numbers of people doing more work." He says the junior production layer took the hardest hit.

Of course it did. The junior layer is precisely the layer AI does cheapest and fastest.

Midjourney Ate Your Art Director's Assistant

A Robert Half survey published this month found that 97% of marketing and creative teams are now using or implementing AI-powered software, from generative tools to AI features baked into Adobe Creative Cloud and Figma. Seventy-seven percent plan to increase investment. The technology is no longer coming. It arrived, settled in, put its feet on the desk.

The economics are remorseless. Where you once needed a junior team to generate fifty ad variants over a fortnight, the machine drafts them in minutes and the senior creative polishes the best three. Superside's own data shows teams doubling design production speed and cutting project costs by up to 70% using AI-augmented workflows. That efficiency is real. The question nobody is asking loudly enough: where does the junior designer go?

This was always the implicit bargain of the creative apprenticeship model. You came in cheap, you did the tedious work, you watched the seniors, you got better. Paul Rand put it plainly enough decades ago: craft is learned by doing the unglamorous thing ten thousand times. Bill Bernbach built his entire agency philosophy around letting young talent fail small before they swung big. The junior placement was the training programme.

Now the unglamorous work has been automated. Nobody has replaced the pipeline.

The Copyright Void Making It Worse

Layer onto this the intellectual property chaos that remains unresolved. In March 2026, the US Supreme Court declined to hear Thaler v. Perlmutter, leaving in place the principle that works created purely by AI, without sufficient human authorship in direction, prompting or alteration, cannot be copyrighted. Good news for human creatives, you might think. Except the practical daily reality at agencies is murkier than a legal ruling can fix.

AI companies are simultaneously embroiled in training-data litigation. The Bartz v. Anthropic class action settled for $1.5 billion earlier this year. Meta secured a partial fair-use ruling in Kadrey. The legal ground is shifting every quarter. Agencies are deploying tools whose copyright status on outputs remains genuinely contested territory, and the junior designer who queries it is told to just get on with the brief.

As one creative director at a mid-sized London shop told me, off the record: "We're running campaigns built on assets that have the legal coherence of a drunken PowerPoint."

The Omnicom Effect and the New Agency Maths

The Omnicom-IPG merger in November 2025 created a combined entity generating $25 billion in annual revenue with over 100,000 employees. Many agency CEOs paused their own M&A activity, watching for divestitures and talent displacement. JP Morgan's commercial banking team, which works across the advertising sector, noted that M&A activity is expected to pick back up in 2026, concentrating in connected TV, retail media and identity infrastructure. Not creative headcount. Infrastructure.

US advertising spend is forecast to reach $414.7 billion this year. The money is there. The platforms are gobbling it. Amazon, Google and Meta have automated targeting, creative optimisation and performance reporting to the point where brands with straightforward direct-response needs can bypass agencies entirely. The agencies left standing are the ones who can prove value through proprietary data, strategic oversight and genuine creative differentiation, none of which you can learn without first spending three years being the person who resizes banners.

The Anthropic Number That Should Scare Everyone

Anthropic's Labour Market Impacts of AI report found that market research analysts and marketing specialists sit among the occupations most exposed to AI, with 64.8% of current marketing tasks potentially able to be automated or supported by AI. Nearly two-thirds. Not the distant future. Now.

Consumer trust in AI creative is eroding, not growing. In 2023, nearly 60% of consumers said they felt comfortable with brands using AI in advertising. By 2024, that figure had fallen to 46%. By the end of 2024, nearly two-thirds of consumers said they felt uneasy about how AI is being used in creative work, with the sharpest scepticism among Gen X and Boomers, who still control the majority of spending power.

So you have a sector deploying AI at near-universal rates to appeal to audiences who are growing less comfortable with it, while cutting the junior staff who would, in ten years, have developed the cultural intelligence to know when the machine is getting it wrong.

2,554 New Agencies and a Vanishing Floor

Back to that Companies House number. 2,554 new advertising agency formations in Q2 2026, down 31.4%. Some of this is consolidation at the top. Some is founders pausing while the dust settles. But some of it, a meaningful slice, is people who would once have incorporated a small creative shop deciding the economics no longer make sense at the bottom.

The Cannes Lions circuit is still handing out metals. The holding companies are still posting revenue. The One Show literally invented a new award category in March 2026 to recognise AI agency innovation. Trophies for the machines, silence for the humans trying to break in.

And that twenty-three-year-old with the brilliant book? She's teaching herself prompt engineering, because that's the only door anyone left ajar.

So here's the question nobody in a corner office wants to answer: if the junior layer is the farm system, and the farm system has been automated, where do your senior creatives come from in 2031?
