Pennsylvania Enacts First-in-Nation AI Advertising Law Requiring Disclosure Labels

Pennsylvania Becomes Pioneer in AI Advertising Regulation

Pennsylvania Governor Josh Shapiro approved the Artificial Intelligence Deceptive Advertising Act on October 22, establishing the state as a frontrunner in regulating AI-generated advertisements1

1

. The legislation, now designated as Act 99 of 2026, takes effect on December 21 following a 60-day implementation period1

1

. State Senator Nick Pisciottano, who introduced the bill in June 2025, secured bipartisan support with the Senate passing it 48 to 2 and the House approving it 163 to 40 on October 71

Mandatory Disclosure for AI-Generated or Significantly Modified Ads

The Pennsylvania AI law targets advertisements containing synthetic content, defined as images, videos, audio clips, or text significantly modified or generated by artificial intelligence1

1

. Advertisers cannot knowingly, recklessly, or willfully distribute such content without labels required for AI ads if it creates false impressions about a product's nature, origin, or authenticity1

1

. The disclosure for AI content must state clearly that the advertisement contains AI-modified or AI-generated material, appearing the first time consumers encounter the content and in the same medium as the advertisement itself1

.

Comprehensive Format Requirements Across Media

Regulating AI-generated advertisements demands format-specific compliance standards. Audio disclosures must be delivered at sufficient volume and pace for comprehension1

1

. On-screen labels must remain visible long enough for viewers to read completely1

1

. Print advertisements, including point-of-sale displays and brochures, require typography that contrasts clearly with background elements1

1

. Where technically feasible, disclosures must be permanent or extremely difficult to remove1

1

. These requirements apply to all advertising shown in Pennsylvania regardless of production location, meaning television commercials created in other states or countries must comply when reaching Pennsylvania audiences2

Strategic Exemptions and Legal Interpretations

The Artificial Intelligence Deceptive Advertising Act includes three categorical exemptions: content that is evidently fictional, works of parody and satire exemptions along with commentary or criticism, and content limited exclusively to text1

1

. Critics question the law's effectiveness given imprecise language around terms like "significantly modified," which remains subjective and open to interpretation2

2

. The broad exceptions for parody, satire, commentary, or criticism may provide advertisers with legal maneuvering space2

2

. The precise definition of "evidently fictional" content also lacks clear boundaries3

3

.

Enforcement Mechanisms and Penalty Structure

The Pennsylvania Office of Attorney General holds primary enforcement authority, with district attorneys also empowered to seek injunctions or initiate civil actions1

1

. Courts can impose civil fines up to $3,000 per violation, plus attorney fees and court costs1

1

. Pisciottano clarified that penalties would target AI companies rather than individual users, placing responsibility on corporations to ensure proper disclosure accompanies their advertising3

3

. The enforcement framework aims to combat false or misleading advertising that has become easier to produce with AI-generated content capabilities2

.

Consumer Protection Drives Legislative Action

The law addresses growing concerns about AI transparency as businesses increasingly deploy AI-generated images to promote products across digital platforms and traditional media3

3

. "Consumers deserve to know if AI is being used to create a false impression about a product or service," Pisciottano stated following the final vote1

1

. Consumer protection motivated the legislation particularly after advocacy groups representing older populations reported scams involving fake AI advertising targeting technologically less-literate demographics3

3

. Pisciottano warned that advancing technology will make distinguishing authentic material from fabricated content increasingly difficult, stating "This technology is only going to get better and better"3

National Implications for AI Regulation

Pennsylvania's move positions the state among the first to establish disclosure requirements specifically for AI-generated advertisements3

3

. "Pennsylvania moved fast on this," Pisciottano noted, adding that only a couple other states currently have similar requirements3

3

. The legislation represents elected officials responding to voter demand to bring artificial intelligence under legislative control, with expectations that either federal government or numerous states will adopt similar measures2

3

. The far-reaching consequences extend beyond state borders as the law applies to any advertisement displayed to Pennsylvania audiences, potentially establishing a precedent for nationwide AI regulation standards. This aligns with broader AI transparency initiatives including OpenAI's ChatGPT text watermarking in the EU and Google's public SynthID detector1
