California enacts SB 1050: mandatory disclosure of AI-generated ad performers

SB 1050, signed 16 September, requires "explicit disclosure on any video or audio advertisement that uses AI-generated performers to sell a product or service," and bars continued use of a non-compliant ad once it is found in violation. It follows New York's synthetic-performer disclosure law and extends California's AI-labelling push from chatbots and companions into advertising specifically. Any organisation running AI-generated or AI-enhanced talent in ads reaching California consumers needs a compliance review of ad creative and takedown procedures now, ahead of enforcement rather than after it.

Newsom EO advances AI 'kill switch,' independent frontier oversight

Newsom's 18 September executive order speeds up implementation of SB 813 and AB 1405, California's frontier-AI safety and independent-auditor laws, and directs the Government Operations Agency to convene experts within two months on strengthening state law, including a 'kill switch' for frontier models "verified on an ongoing basis by an independent verification organization" and updated definitions of critical safety incidents. This is a planning and rulemaking directive, not a new statute, but it signals where California's audit regime is heading. Any organisation running frontier models with a California footprint should track the two-month recommendations for what "independent verification" and kill-switch efficacy will actually require operationally.
