Where this applies
United States payroll employment at agencies — advertising, PR, media buying, display and direct mail in one number. Marketers employed by the brands themselves are counted in their employer's industry and not here, so the long shift of marketing in-house, which began well before these tools, shows up in this line as a fall regardless of anything AI did. The peak is February 2023, three months after ChatGPT, and the decline is gradual rather than a break: 503,200 to 476,000 over three and a half years, about 5%. That is a real contraction and a slow one, and the series cannot say how much of it is tools, how much is in-housing, and how much is advertising budgets. Seasonally adjusted, monthly, in thousands; recent months preliminary.
What this means
Agency-side employment turned down three months after ChatGPT and has fallen every year since — about 5% over three and a half years. It is a real contraction, and it is slow: no month looks like a break, which is what a technology shock is usually imagined to look like.
What it does not yet show
It cannot separate three things that all push the same way: tools, the long move of marketing in-house, and advertising budgets. In-housing is the one to hold on to — a marketer who moves from an agency to the brand disappears from this series and has not lost their job. Put beside the graphic design services series from the same night, agencies fell about 5% while graphic design services fell about 13% over the same months, which is a difference worth explaining before either number is used.
What you can check
Count the job postings on one agency's careers page and one comparable brand's, in the same discipline, and check both again in three months. If the agency shrinks while the brand grows, you are watching in-housing, not replacement.
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
