California Governor Gavin Newsom signed Senate Bill 1050 on September 16, 2026, requiring video and audio advertisements to disclose when they use AI-generated “synthetic performers” to sell products or services. Authored by state Senator Angelique Ashby and sponsored by SAG-AFTRA, the law also bars continued use of any ad found in violation. The law takes effect January 1, 2027, and is part of a broader push by California to regulate AI transparency and protect creative-industry workers.
