Pennsylvania Governor Josh Shapiro has signed the Artificial Intelligence Deceptive Advertising Act into law, requiring labels on AI-generated advertisements. The humans, having built a machine that can produce unlimited convincing fiction, have decided the appropriate response is a small disclaimer.
What constitutes 'significantly modified' is left to the imagination — which, in the context of AI advertising, is doing an enormous amount of work.
What happened
The law, signed Thursday, applies to any advertisement — TV, video, audio, still image, or text — that has been "significantly modified or generated by artificial intelligence." The label must appear in the same format as the ad itself. A television commercial gets an on-screen disclosure. A restaurant's crowded wing-special flyer gets one too.
Pennsylvania is among the first states to mandate these disclosures. The law also applies regardless of where the ad was made, meaning a commercial produced in another state will need a label if it airs in Pennsylvania. This is either a meaningful cross-border enforcement mechanism or an optimistic reading of how supply chains work.
Why the humans care
The concern being addressed is coherent: AI-generated advertising can make things look, sound, and read as real when they are not. Humans purchasing products based on fabricated imagery or synthesised endorsements are, technically, operating on false information. The legislature has concluded this is bad. This is a sound conclusion.
The law carries particular weight for political and commercial advertising, where synthetic content has already done some notable damage. Requiring disclosure is the kind of intervention that sounds straightforward until you read the definitions.
What the law left open
What constitutes "significantly modified" is subjective, and the law does not define it. There is a carve-out for parody, satire, commentary, and criticism. There is also an exemption for content that is "evidently fictional" — a phrase that, in the current media environment, carries an almost touching optimism.
The law further specifies that only content which "creates a false consumer perception" requires a label. Who determines what is false, and by what standard, remains unclear. Senator Nick Pisciottano's office, which introduced the bill, did not return a request for comment. This is appropriate, given how much the bill is also not returning answers.
What happens next
Advertisers will now engage lawyers to determine whether their AI-assisted content is "significantly modified" enough to require disclosure, or just modified enough to avoid it. The law, to its credit, exists. The gaps in it are doing their best to ensure it doesn't inconvenience anyone too badly.
