SB 1050, Sen. Angelique Ashby’s bill making undisclosed AI “synthetic performers” in advertising an unlawful practice, is on its way to Gov. Gavin Newsom’s desk as the California Legislature prepares to adjourn Aug. 31. The bill routes enforcement through Business and Professions Code Sections 17200 and 17500, meaning noncompliance is false advertising, not a policy footnote.

The mechanics matter for anyone buying ad creative. A “synthetic performer” is a human-like digital figure, voice, or representation generated with AI or machine learning that doesn’t depict an identifiable real person under Civil Code Section 3344. “Prominent” means foreground: demonstrating the product, narrating on- or off-camera, or reacting to the pitch. Trigger those, and the ad must carry wording substantially similar to “this performance features a synthetic performer” or “no human performer is depicted.” A static AI-generated background behind a live human presenter, by contrast, likely doesn’t.

The path here has been fast. The Senate approved it May 28. Assembly Appropriations cleared it 12-1 on Aug. 13, and it was amended and ordered to third reading Aug. 19. Per the Transparency Coalition’s Aug. 28 update, Newsom has 30 days after adjournment, until roughly Sept. 30, to sign or veto. It joins AB 2025, the real-estate AI disclosure bill sent to Newsom on Aug. 25, with 21 other AI-related measures still pending. See the Assembly floor vote, the small-business exposure, the countdown to Newsom, and the broader bill sprint.

The compliance burden lands on the human who approves the ad before it runs. Small businesses relying on human approval before ads go live, the checkpoint LemonLime builds into its prepared marketing content, have a natural place to add the required label. Autonomous-publishing pipelines don’t.

Sacramento’s AI decade is now California’s advertising law.
