SB 1050 makes it unlawful in California to create or distribute an advertisement that uses a "synthetic performer" without a clear and conspicuous disclosure that the performer is synthetic. The bill defines key terms, prescribes minimum disclosure placement and wording, and exempts expressive works when the promotional use matches the work itself.
The statute folds violations into California's existing false-advertising framework (Section 17500) and allows enforcement through the Unfair Competition Law (commencing with Section 17200). That combination imposes both operational compliance demands on advertisers and ad platforms and litigation risk through civil enforcement and private suits.
At a Glance
What It Does
The bill bars use of AI‑generated, human‑like performers in ads unless a disclosure that the performer is synthetic appears close to the performer and remains long enough for a reasonable consumer to notice. It prescribes sample wording and sets minimum presentation criteria.
Who It Affects
Advertisers, ad agencies, digital platforms that place or host ads, and creators who produce synthetic voices or figures for commercial messaging in California. Media buyers and programmatic vendors that deliver ads into California impressions will also need to adjust operations.
Why It Matters
SB 1050 is an early statutory attempt to mandate AI transparency in commercial content and routes enforcement through California's robust consumer‑protection tools, increasing the practical and legal costs of using synthetic talent in advertising.

What This Bill Actually Does
SB 1050 starts by defining three terms that frame the rest of the law: what counts as an "advertisement," what makes a disclosure "clear and conspicuous," and what the statute means by "synthetic performer." "Advertisement" is broadly drawn to cover messages and digital communications intended to induce purchases, which brings online and platform-based ads squarely within the rule. The "synthetic performer" definition targets human‑like digital figures, voices, or representations created using AI or computational techniques and explicitly excludes depictions of identifiable natural persons as defined in Civil Code § 3344.
The core obligation is short and direct: anyone who creates or disseminates an ad with a synthetic performer in California must include a disclosure that the performer is synthetic. The bill sets three minimum requirements for that disclosure: it must appear close to the performer, be displayed long enough and in a manner a reasonable consumer can notice and understand, and use wording substantially similar to the examples the bill provides (for instance, "this performance features a synthetic digital performer" or "no human performer is depicted").
Those criteria aim to leave limited room for obscure or buried labeling.SB 1050 also builds explicit guardrails. It does not prohibit generating or showing synthetic content; instead, it limits regulation to the factual requirement of disclosure rather than the expressive content of the ad.
The bill contains an express exception for advertisements for expressive works—movies, TV shows, video games, and similar audiovisual works—so long as the use of a synthetic performer in the ad is consistent with its use in the underlying work. Finally, the statute makes a violation a violation of California's false advertising law (Section 17500) and therefore enforceable under the Unfair Competition Law, meaning civil actions, injunctions, and restitution remedies are available.For practitioners, the practical reach is immediate: marketers must map where synthetic performers appear and ensure labeling meets the proximity, duration, and wording tests across formats (video, audio, static images, programmatic placements).
Platforms that host or serve ads into California should consider policy and product changes to support such disclosures. The exclusion of depictions tied to identifiable natural persons points to a parallel regulatory terrain—image‑right and anti‑impersonation claims—rather than creating overlap that would force double‑labeling in those cases.
The Five Things You Need to Know
The bill requires disclosure language substantially similar to the provided examples, such as “this performance features a synthetic digital performer” or “no human performer is depicted.”, A disclosure must appear in close proximity to the synthetic performer and be presented for a duration and in a manner sufficient for a reasonable consumer to understand the performer is not human.
The statute defines "synthetic performer" as AI‑created human‑like figures or voices that are not based on or intended to depict an identifiable natural person under Civil Code § 3344.
Advertisements for expressive audiovisual works (films, TV, streaming, video games, documentaries) are exempt if the synthetic performer's use in promotional material is consistent with its use in the underlying work.
A violation of the disclosure requirement is treated as a violation of Section 17500 and is enforceable under the Unfair Competition Law (beginning with Section 17200), enabling civil suits, injunctions, and restitution.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Key definitions: advertisement, disclosure standard, synthetic performer
This subsection sets the vocabulary the rest of the bill uses. "Advertisement" is intentionally broad to capture digital and online formats that might otherwise evade traditional advertising rules. "Clear and conspicuous disclosure" borrows consumer‑protection language but frames it against the medium and context. The "synthetic performer" definition targets AI‑generated human‑like representations and explicitly references Civil Code § 3344 to exclude depictions tied to identifiable natural persons, which channels identity‑based claims to existing image‑rights law instead of this disclosure requirement.
Flat prohibition without disclosure
Subdivision (b) makes it unlawful to use a synthetic performer in an advertisement in California unless the law's disclosure standard is met. Practically, this shifts the default: synthetic performers are permitted but require affirmative labeling. The prohibition applies whether the advertiser created the synthetic asset or caused it to be used, which implicates clients, production houses, and distribution partners across the ad supply chain.
Minimum disclosure content and presentation requirements
This subsection lists three minimum elements for a compliant disclosure: proximity to the performer, sufficient presentation time/format for a reasonable consumer to understand, and use of wording substantially similar to two examples the bill provides. The statute leaves key interpretive questions to implementation and courts—how close is "close proximity," what counts as "sufficient" duration, and how strictly courts will read "substantially similar"—but it does reduce compliance ambiguity by giving concrete example labels.
Expressive‑work and content boundaries
Subdivision (d) contains four non‑application points: it does not ban synthetic content; it limits regulation to factual disclosures rather than message content; it preserves other remedies under Sections 17200 and 17500; and it exempts advertisements for expressive works where the promotional use matches the work's use. That exemption narrows the bill's reach in entertainment advertising but creates a gatekeeping line that advertisers will need to justify when relying on it.
Enforcement under existing false‑advertising law and severability
Subdivision (e) ties violations to Section 17500, which the bill makes enforceable via the Unfair Competition Law framework; this opens the door to civil litigation, injunctive relief, restitution, and actions by public prosecutors and private plaintiffs. Subdivision (f) states standard severability language so that if a court invalidates one part, the remainder survives—an important drafting choice given ongoing constitutional and preemption questions in similar statutes.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- California consumers concerned about deception — clearer labeling reduces the risk of being misled by human‑like synthetic talent in commercial messages.
- Performers and talent agencies that rely on human authenticity — disclosure can protect the market value of real performers by preventing consumer confusion.
- Advertisers that adopt transparent practices early — clear labeling reduces downstream litigation risk and can serve as a trust signal with consumers and regulators.
- Consumer protection plaintiffs and regulators — the bill creates a straightforward statutory hook for enforcement under existing false‑advertising law.
Who Bears the Cost
- Advertisers and creative agencies — they must audit creative pipelines, add disclosure assets, and change production and delivery workflows to meet proximity and duration requirements.
- Digital platforms and ad networks — they will need product changes (UI/UX support for labels), policy updates, and potentially content‑delivery rules to ensure disclosures persist across placements and geographies.
- Small creators and indie producers — the compliance work and potential need for legal review create disproportionate burdens compared with large advertisers that can absorb operational changes.
- Media buyers and programmatic vendors — ensuring disclosures travel with impressions, across redirects and dynamic ad insertion, will raise technical and contractual complexity.
Key Issues
The Core Tension
The bill forces a trade‑off between consumer transparency and operational/expressive flexibility: making synthetic performers unmistakable protects consumers but imposes fuzzy technical standards and compliance burdens that could chill innovative ad formats or create litigation around what counts as adequate disclosure.
SB 1050 is deliberately concise, but that concision transfers interpretive weight to courts, platforms, and compliance teams. Key terms—"close proximity," "sufficient duration," and "reasonable consumer"—are standard consumer‑protection phrases but are fact‑specific; they will generate litigation and guidance as parties test boundaries in short‑form video, audio‑only ads, banner rotations, and programmatic feeds.
The bill's sample wording reduces one vector of ambiguity, but the "substantially similar" qualifier invites disputes over minor phrasing changes and translation issues in multilingual campaigns.
The exemption for advertisements tied to expressive works is a practical carve‑out for entertainment marketing, but it also creates a potential loophole. An advertiser could characterize a commercial spot as tied to an expressive work to avoid labeling; whether that defense holds will depend on facts about consistency of use.
Another unresolved issue is cross‑border delivery: ads served globally but viewable in California impressions pose jurisdictional and technical questions about how to present geographically targeted disclosures without breaking delivery logic. Finally, the statute's choice to exclude synthetic depictions of identifiable persons from this disclosure regime channels those cases into image‑rights law, leaving a doctrinal patchwork where some deepfakes are covered by disclosure rules and others are governed by separate tort and statutory regimes.
