New law forces advertisers to label synthetic performers, says Newsom

California's new law forces ads to reveal when AI actors are used, protecting viewers and the state's creative workforce.

New law forces advertisers to label synthetic performers, says Newsom

The California State Legislature has taken another step toward regulating artificial intelligence in the public sphere. Governor Gavin Newsom signed Senate Bill 1050 into law, a measure that obliges any commercial video or audio spot that employs an AI-generated performer to include a clear on-screen disclaimer. The signing ceremony took place at the Los Angeles headquarters of SAG-AFTRA, the union representing film and television talent, underscoring the legislation’s focus on safeguarding both consumers and creative professionals.

Under the new statute, commonly referred to as the Advertisement Integrity Act any synthetic figure—whether a digitally fabricated face, voice, or full-body avatar—must be identified as such whenever it appears in an advertisement for a product or service. Failure to comply triggers an immediate prohibition on the offending ad, and violators may face misdemeanor penalties. The law expands California’s existing list of deceptive marketing practices, treating undisclosed AI performances on par with traditional false-advertising tactics.

Key provisions and what they mean for advertisers

The bill defines a synthetic performer as a computer-generated entity that mimics human appearance, speech, and motion to a degree that it can be mistaken for a real person. Advertisers are required to place the disclosure in a location that is “clear and conspicuous,” ensuring that viewers cannot miss it before the persuasive content unfolds. The legislation also mandates that once an ad is found to be non-compliant, it must be withdrawn from all platforms, including broadcast, streaming, and digital networks, until the required label is added.

Beyond consumer protection, SB 1050 aims to preserve job opportunities for human actors, voice-over artists, and other performers whose livelihoods could be threatened by unchecked AI substitution. By mandating transparency, the law seeks to prevent a scenario where brands replace human talent with cheaper synthetic alternatives without informing the public.

Reactions from labor groups and lawmakers

SAG-AFTRA hailed the measure as a victory for the “creative economy,” emphasizing that real people are the heartbeat of California’s entertainment industry. Duncan Crabtree-Ireland, the union’s National Executive Director, noted that the language of the bill was crafted with direct input from performers, ensuring that the disclosure requirement would be both practical and enforceable. Senator Angelique Ashby, the bill’s author, called the enactment a “necessary guardrail” that protects both consumers and workers from deceptive AI practices.

While labor advocates praised the law, some industry voices expressed reservations. Representatives from TechNet and the Motion Picture Association argued that the bill’s language is overly broad, suggesting that disclosure should be limited to instances where the synthetic element actually misleads the audience. They urged lawmakers to tie the requirement to material deception rather than a blanket labeling rule. Nonetheless, the bill passed both chambers with bipartisan support, reflecting a growing consensus that AI-driven advertising needs clear oversight.

California’s broader AI regulatory framework

SB 1050 does not exist in isolation. It builds on a series of AI-focused statutes that Governor Newsom has signed over the past few years. In 2024, the state enacted the California AI Transparency Act which requires companies to watermark AI-generated media and provide detection tools so users can assess whether content has been altered by artificial intelligence. Subsequent laws such as Senate Bill 813 and Assembly Bill 1405 introduced mandatory third-party audits and independent verification for high-risk AI systems.

These measures position California as the nation’s most aggressive regulator of frontier AI technology. The state’s framework also includes protections for child users of AI chatbots, requirements for whistleblower protections in AI safety matters, and a transparency mandate for deep-fake content. Comparatively, New York enacted a similar disclosure rule earlier this year, imposing fines of up to $5,000 per violation. California’s approach, however, couples the labeling requirement with broader consumer-privacy safeguards and labor-rights considerations, signaling a more holistic strategy.

As AI continues to blur the line between human and machine, the new law serves as a practical checkpoint for advertisers while reinforcing California’s reputation as a leader in technology governance. Stakeholders across the entertainment, tech, and marketing sectors will now have to adjust their workflows to incorporate the required disclosures, ensuring that audiences can distinguish between genuine talent and synthetic creations.
