California AI Synthetic Performer Ad Law

Overview

California SB 1050, authored by Senator Angelique Ashby during the 2025-2026 legislative session, is Chapter 246, Statutes of 2026. Its official long title is 'An act to add Article 10 (commencing with Section 17610) to Chapter 1 of Part 3 of Division 7 of the Business and Professions Code, relating to consumer protection.' Governor approval and filing with the Secretary of State occurred on September 16, 2026. The non-urgency statute takes effect January 1, 2027, and is awaiting entry as of October 20, 2026.

The chaptered act adds Article 10, Synthetic Performers, and requires a factual disclosure when a person creates and causes publication, through an advertising medium, of an advertisement prominently including a synthetic performer. It operates within existing false advertising and unfair competition law, not a separate AI licensing system. The Legislature identifies consumers' substantial interest in knowing when synthetic performances are reasonably interpretable as human performances and intends a purely factual commercial disclosure to prevent deceptive advertising while respecting constitutional commercial-speech protections. The act neither prohibits synthetic content nor requires human performers. A separate component obliges advertising media served with qualifying court orders to discontinue specified dissemination and payment acceptance.

Definitions

Section 17610(a)(6) defines a synthetic performer as a digital figure, voice, or representation created wholly or partly using generative artificial intelligence that creates a realistic impression of a human performer's audio, audiovisual, or visual performance and is not recognizable as any identifiable natural person. Under Section 17610(a)(4), generative artificial intelligence is a system capable of generating derived synthetic content, including text, images, video, and audio, emulating the structure and characteristics of its training data. Prominence under Section 17610(a)(5) includes foreground demonstration or illustration of a product or service; providing or voicing on- or off-camera narration or a commercial message; or illustrating or reacting to that narration or message.

Section 17610(a)(1) covers audio, video, and audiovisual messages, statements, audiovisual recordings, digital communications, and other representations disseminated by any means, including online platforms, intended or reasonably expected to induce purchases of goods or services as described in Section 17500. An advertising medium under Section 17610(a)(2) includes broadcasters, cable operators, multichannel video programming distributors, platforms, streaming services, advertising networks, publishers, and other entities making audio or audiovisual advertising available to California consumers. Entities incapable of removing advertisements, disabling access, or stopping further dissemination are excluded. Section 17610(a)(3) requires a clear and conspicuous disclosure to be difficult to miss, easily understandable, and noticeable, readable, and comprehensible to a reasonable consumer considering the advertisement's medium, format, and context.

Governance and Institutional Framework

The act relies on existing consumer protection institutions and courts. Section 17610(f) makes a violation of the section a violation of Section 17500 and permits enforcement under Chapter 5, commencing with Section 17200, of Part 2. It establishes no dedicated regulator, registration authority, certification program, or administrative approval mechanism. For the advertising-medium duties, a court of competent jurisdiction must issue an order finding that an advertisement violates the relevant chapter or enjoining its creator from publishing it. Qualifying orders expressly include, but are not limited to, injunctions under Code of Civil Procedure Section 527.

Responsibilities depend on conduct and operational capacity. Section 17610(b) applies to any person creating and causing publication of a covered advertisement, not just AI developers. Section 17610(e) separately governs advertising media after service of a qualifying order and sufficient identifying information. It does not create an independent duty for every medium to screen all advertisements before publication. Section 3 provides that local-government reimbursement is unnecessary because the relevant local costs arise from changes to criminal prohibitions or definitions under the specified constitutional and Government Code framework.

Key Focus Areas

The central requirement concerns realistic synthetic human performances used to sell goods or services. Section 17610(c) requires wording substantially similar to 'this performance features a synthetic performer' or 'no human performer is depicted.' Exact reproduction is not mandatory, but alternative wording must convey substantially similar information and meet the clear-and-conspicuous standard. The act prescribes no universal font size, display duration, audio volume, placement, or technical labeling format. Adequacy depends on whether a reasonable consumer would notice, read, and comprehend the disclosure in the particular medium, format, and context.

The law does not require labeling every AI-assisted advertisement. The performer must satisfy both the statutory definition and a prominence alternative. Voice-only narration can qualify without foreground visual placement. Because the definition excludes representations recognizable as identifiable natural persons, digital replicas of specific people should not automatically be classified as synthetic performers under this section; other rights and remedies remain applicable. Section 17610(d) preserves synthetic content creation, distribution, and exhibition and limits regulation of advertisements' expressive or informational content to the factual disclosure requirement. Compliance does not authorize otherwise deceptive advertising.

Implementation Framework

Compliance begins by determining whether a communication induces or is reasonably expected to induce purchases, whether its figure or voice satisfies the synthetic-performer definition, and whether that performer meets a prominence criterion. If Section 17610(b) applies, the person creating and causing publication must include the required disclosure. Reviewing the disclosure in its actual delivery formats supports assessment of the context-dependent visibility and comprehension standard. Campaign inventories, internal sign-offs, and review procedures are recommended controls, not statutory recordkeeping, testing, or certification duties.

Two exclusions require separate analysis. The section does not apply to advertisements for expressive works, including motion pictures, television programs, streaming content, documentaries, video games, and similar audio or audiovisual works, when the synthetic performer's advertising or promotional use is consistent with its use in the expressive work. It also excludes advertisements whose generative AI use solely involves language translation of a human performer or other accessibility features. Advertising media should establish processes for receiving qualifying court orders, identifying affected advertisements, stopping California dissemination, and stopping payment acceptance for further dissemination. These controls support the express duties without creating a general platform monitoring mandate.

Monitoring and Evaluation

SB 1050 requires no periodic compliance reports, external audits, AI model evaluations, impact assessments, or public synthetic-performer registry. Monitoring can focus on the prohibition's elements: a qualifying advertisement, qualifying synthetic performer, prominence, and adequate disclosure. Reviews should examine delivered advertisements rather than production files alone because disclosure adequacy depends on medium, format, and context. Internal explanations of scope and exclusion decisions may support compliance, but the act specifies no documentation contents, retention periods, or reporting schedule.

Advertising-medium obligations arise from judicial action and service, not merely allegations of undisclosed synthetic performers. Section 17610(e)(1) requires a qualifying court order served with information reasonably sufficient to identify the advertisement. The medium must then remove it, disable access, or cease further dissemination in California and cease accepting payment for further dissemination as soon as commercially reasonable and technically feasible. No fixed number of hours or days is prescribed. Tracking receipt, identification, technical action, and payment cessation is a recommended operational safeguard, not a separate reporting obligation.

Penalties, Liability, and Appeals

Section 17610(f) incorporates Section 17500's false advertising framework and permits enforcement through the unfair competition chapter commencing with Section 17200. The Legislative Counsel's Digest explains that existing false or misleading advertising prohibitions carry misdemeanor consequences and that expanding the crime's scope creates a state-mandated local program. SB 1050 establishes no standalone monetary penalty, damages multiplier, per-advertisement fine, or new sentencing range. Monetary, criminal, and equitable consequences depend on the incorporated framework and the particular proceeding, not a new penalty schedule in Section 17610.

The statute preserves rights and remedies under Sections 17200 and 17500 and other laws concerning deceptive, unfair, or misleading business practices. A qualifying order triggers advertising-medium cessation duties only after the service and identification conditions are satisfied. The act creates no special administrative appeal body, bespoke appeal deadline, or procedure for contesting an order; challenges follow otherwise applicable judicial processes. Section 17610(g) makes the requirements severable: invalidating a provision or application does not invalidate provisions or applications capable of operating independently. Disclosure is therefore not immunity from other advertising-law claims.

Relationship to Other Instruments

Section 17500 informs the advertisement definition and supplies the violation incorporated by Section 17610(f). Chapter 5 commencing with Section 17200 provides an enforcement route, while Section 17610(d)(3) preserves existing consumer protection rights and remedies. Code of Civil Procedure Section 527 is expressly identified as a possible source of a qualifying injunction. Section 3 invokes Article XIII B, Section 6, of the California Constitution and Government Code Section 17556 to explain why reimbursement is unnecessary for specified local costs associated with changes to criminal prohibitions or definitions.

The Governor's signing announcement places SB 1050 within California's broader work on AI transparency and performers' digital likenesses. These policy connections do not incorporate other instruments' watermarking, detection-tool, consent, or contract requirements into Section 17610. This act addresses realistic synthetic performers not recognizable as identifiable natural persons and requires consumer-facing factual disclosures in qualifying advertisements. It does not create digital-replica licensing rights, employment guarantees, or a prohibition on replacing human performers. Separate obligations must be evaluated independently rather than presumed satisfied by disclosure.

National/Federal Alignment

SB 1050 is a California consumer protection statute, not a federal AI or telecommunications regulation. The advertising-medium definition concerns audio or audiovisual advertisements available to California consumers, and the court-order provision requires removal, disabled access, or cessation of further dissemination in this state. Broadcasters, cable operators, multichannel distributors, streaming services, and platforms are covered through functional definitions, not amendments to federal communications licensing. The act assigns no enforcement role to a federal agency, establishes no federal reporting channel, and requires no federal approval of advertisements or AI systems.

The Legislature's intent to require a purely factual commercial disclosure consistent with constitutional commercial-speech protections explains the disclosure-based approach and preservation of synthetic content creation. It is not a judicial determination resolving every constitutional challenge. The act establishes no mutual recognition with federal labeling requirements and does not provide that satisfying a federal advertising rule automatically satisfies Section 17610. No particular federal AI instrument is incorporated. Federal requirements, jurisdictional questions, and potential preemption issues require separate assessment; the act establishes no definitive comparison with a specific federal rule.
