Pennsylvania Governor Josh Shapiro signed the Artificial Intelligence Deceptive Advertising Act into law on Thursday, mandating that advertisements significantly modified or generated by artificial intelligence include specific disclosures. The legislation applies to all media formats, including still images, video, audio, and text, requiring labels to match the format of the ad itself. This requirement extends to a wide range of commercial content, from television commercials produced by multi-billion-dollar corporations to local flyers for restaurant specials. Pennsylvania becomes one of the first states to impose such disclosure requirements on AI-generated content. The law mandates these labels regardless of where the advertisement is placed.
