Pennsylvania businesses have less than six weeks to comply with one of the first state laws in the country regulating AI in advertising. The Artificial Intelligence Deceptive Advertising Act, signed by Governor Josh Shapiro on October 22, takes effect on December 21 — and while its stated goal is simple, its actual requirements are narrower and more ambiguous than many advertisers assume, according to an explainer published this week by WHYY and legal analysis from Inside Global Tech.
What the Law Requires
The law requires disclosure of AI use in advertisements — but only in specific circumstances. It does not demand a label on every ad that touched an AI tool. Instead, disclosure is required when AI-generated content creates what the statute calls "a false consumer perception" about the product being advertised.
"It's not every minor digital edit," state Senator Nick Pisciottano, the Democratic sponsor who represents parts of Allegheny County, told WHYY. "It's specific to AI-generated content that creates a false consumer perception."
Pisciottano said he drafted the law in response to the explosive growth of AI-generated content online, which he argued makes it harder for consumers to tell what is real — and easier for people to be scammed. "We should step in and make some kind of reasonable rules and regulation around AI to make sure folks know [whether] what they're seeing is either generated by AI or not," he said.
Anyone publishing or marketing online now faces a patchwork of state-level rules like this one — a regulatory reality we follow closely in our AI policy coverage as disclosure laws spread from state capitols to national platforms.
The Gap Between Rhetoric and Text
Public statements from state leaders have described the law more broadly than its text does. In a Facebook post announcing his signing of the bill, Governor Shapiro framed it as a straightforward transparency mandate: "Pennsylvanians deserve to know if and when AI is being used in ads — and now, thanks to this new law, any advertisement in the Commonwealth that uses AI technology must make that crystal clear."
Pisciottano made a similar statement when the law passed, saying ads generated by AI would "have to put a disclaimer at the bottom that says this was generated by AI."
But the statute itself is narrower, and that gap has caught the attention of advertising lawyers. "What [the law] says and what its goal might be could be different things," said Libby O'Neill, an advertising and AI attorney with the law firm Loeb & Loeb, in comments to WHYY. "The sponsor has described this as, 'If it's AI, label it.' The law, on the other hand, only requires a label if that AI use creates a false perception about the product, and we don't really know what 'false perception' means in this context."
The ambiguity appears to be an artifact of the legislative process. According to WHYY's review of earlier versions of the bill, the measure was originally conceived as a mandate to label all AI-generated content in ads; the "false perception" qualifier was added later, in amendment, narrowing the final scope.
Why Pennsylvania Passed It Now
The law arrives amid widespread frustration with so-called AI slop in commercial content. WHYY documented the local backdrop: Philadelphia-area restaurants have faced online backlash after being accused of using AI-generated images in signage, social posts, and ads — with critics arguing that fake food photos mislead customers and undercut local photographers.
Some accused businesses denied using AI. Starting December 21, the law gives Pennsylvania consumers a statutory hook for that argument when AI-generated imagery creates a false impression of what a business actually offers.
The Pennsylvania measure is one of the first state laws of its kind in the United States, but it is unlikely to be the last. State legislators across the country have introduced AI disclosure bills covering advertising, elections, and entertainment, and the December 21 effective date will make Pennsylvania an early test case for how such rules are enforced in practice.
What Advertisers Should Watch
Until Pennsylvania regulators or courts define "false consumer perception," the practical compliance question is case-by-case: whether a reasonable consumer would come away with a materially false impression of the product because of AI-generated content. Cosmetic edits and background touch-ups are unlikely to trigger the law, while AI fabrications of the product itself — a dish the restaurant does not serve, a hotel room that does not exist — sit squarely in the statute's target zone.
The law also leaves open who bears responsibility when an ad violates it — the business featured, the agency that produced the creative, or the platform that ran it. WHYY noted that enforcement mechanics remain open questions heading into the effective date.
For businesses advertising in Pennsylvania, the safest reading of the next six weeks is this: the law will not ban AI in advertising, but it will penalize AI used to make a product look like something it is not. Advertisers with AI-heavy creative pipelines have until December 21 to audit which assets are synthetic, and to document why each use would not create a false perception in the eyes of a consumer.
