Streaming viewers in California who have grown tired of scrambling for the remote when ads blast at higher volume than the show they are watching just got a direct answer from state lawmakers. Governor Gavin Newsom signed SB 576 on Oct. 6, 2025, making California the first state to extend federal broadcast ad-volume rules to streaming platforms such as Netflix and Hulu. The law takes effect July 1, 2026, and bars covered services from transmitting commercial audio louder than the programming it accompanies.
How SB 576 Extends Broadcast Volume Rules to Streaming
For more than a decade, traditional cable and satellite providers have operated under the federal CALM Act, which requires that commercials air at the same average loudness as surrounding content. The FCC enforces this through federal loudness rules, a regulation that references the ATSC A/85 technical standard for measuring audio levels. Streaming services, however, have never been subject to that requirement because the original statute targeted multichannel video programming distributors, not internet-delivered content.
The text of SB 576 closes that gap at the state level. The bill applies to any video streaming service that serves California consumers, and it adopts the same technical framework already governing broadcast and cable ads. That means platforms will need to measure and control ad loudness using the A/85 methodology, the same yardstick cable operators have used since 2012. The practical result for viewers: ad breaks on ad-supported tiers from Netflix, Hulu, Peacock, and similar services should no longer spike noticeably above program volume after mid-2026.
A reasonable expectation is that major platforms will apply a single loudness standard across all U.S. viewers rather than engineer a California-specific audio pipeline. Building and maintaining separate ad-delivery systems for one state would add cost and complexity with little upside. If that prediction holds, California’s law could produce a nationwide reduction in streaming ad-volume swings within roughly 18 months of the effective date, even though the statute technically covers only California households.
Legislative Path and the Federal Standard SB 576 Borrows
The bill moved through the California legislature over the spring and summer of 2025. The Assembly Committee on Privacy and Consumer Protection held a hearing on June 24, 2025, where lawmakers reviewed federal enforcement data and state-level complaint trends tied to streaming ad volume. Committee records show that supporters framed the measure as a straightforward consumer-protection fix: the same loudness guardrails that apply to a cable commercial during a football game should apply to an ad that plays before a show on a streaming app.
Legislative analyses emphasized that the bill does not attempt to reinvent audio engineering standards. Instead, it effectively imports the existing federal benchmark into state law by pointing streaming providers toward the same ATSC A/85 measurements that cable and satellite operators already use. That alignment was central to the argument that SB 576 would be relatively simple to implement for large companies that already maintain broadcast-compliant workflows somewhere in their organizations.
The governor’s office described the signing as a response to persistent viewer frustration. “Californians have had enough of having to reach for the remote every time an ad comes on,” the announcement stated. By tying the new obligation directly to the existing federal rule, lawmakers avoided creating a novel measurement regime. Platforms already familiar with A/85 compliance in their linear-TV operations can, in theory, extend those workflows to their streaming ad stacks without inventing new tools.
Open Questions for Platforms and Enforcement After July 2026
Several gaps in the public record leave the law’s real-world bite uncertain. No official legislative or regulatory text released so far has spelled out, for example, how California agencies will test compliance in a streaming context, where ads may be dynamically inserted and personalized for each viewer. It is also unclear whether the state will rely primarily on consumer complaints, spot checks, or technical audits of provider systems.
Another unresolved issue is how the law will treat edge cases such as user-generated content hosted on large platforms, interactive ad formats, or sponsorship messages that are baked directly into shows rather than delivered as separate ad files. The statutory language focuses on “commercial audio,” but the boundaries of that category on modern streaming services can be blurry. Providers may seek clarification or safe-harbor guidance as the effective date approaches.
Smaller and mid-sized streaming services could face disproportionate implementation costs. While global platforms may already have internal tools to normalize audio to A/85 standards, niche services that rely on third-party ad networks might need to upgrade encoding pipelines, renegotiate ad-tech contracts, or deploy new monitoring systems. Those expenses could influence which services choose to offer ad-supported tiers in California after July 2026.
Enforcement will run through state consumer-protection mechanisms rather than the Federal Communications Commission. Californians looking for official information about the rollout are likely to find updates and agency contacts through the state’s main government portal, which aggregates regulatory announcements and consumer resources. Any implementing regulations or guidance documents are expected to clarify penalties, complaint procedures, and timelines for corrective action when violations occur.
For viewers, the ultimate test will be experiential rather than technical: whether ad breaks on streaming finally feel as even and predictable as those on traditional television. If SB 576 delivers on that promise-and if major platforms extend the same volume practices nationwide-the California experiment could become a de facto standard for streaming ad loudness well beyond the state’s borders.
