Pennsylvania has enacted a law requiring disclosure of AI use in deceptive advertising generated or significantly altered by AI. According to The Verge, it covers images, video, audio and text, and can apply to advertising aimed at state residents regardless of where it was produced. Disclosures must suit the medium, with exceptions including satire, criticism and clearly fictional content. Questions remain about what counts as a significant alteration and a false impression of a product or service. The law should not be read as a blanket ban on AI-assisted advertising or as evidence that the disclosure requirement has already taken effect.
