Pennsylvania Passes AI Deceptive Advertising Act Requiring Labels on AI-Generated Ads

Pennsylvania has enacted legislation requiring that AI-generated content used in advertising be clearly labeled as such, making it one of the first U.S. states to impose mandatory disclosure requirements specifically on AI-produced commercial media. The law targets deceptive use of synthetic media in consumer-facing advertising, with enforcement mechanisms tied to existing deceptive advertising statutes. For developers and product teams building generative AI tools used in marketing, creative, or advertising workflows, this creates a concrete compliance requirement in at least one major U.S. market. Teams shipping AI content generation features to B2B customers in advertising or media verticals will need to evaluate whether their tooling surfaces adequate disclosure mechanisms. The law is likely to be watched as a model — or counterexample — as other states consider similar regulations.
