California’s loud streaming ads law came into force on 1 July, closing a regulatory gap that had left streaming platforms exempt from the volume rules Congress imposed on broadcast and cable television more than a decade ago.
SB 576 prohibits streaming services from airing advertisements louder than the video content they accompany. The standard it sets is specific: compliance must be consistent with the Federal Communications Commission’s regulations under the Commercial Advertisement Loudness Mitigation Act, known as the CALM Act (Public Law 111-311), which has governed broadcast stations and cable operators since 2010. Streaming platforms, as Governor Gavin Newsom noted when he signed the bill on 6 October 2025, had previously sat outside those federal rules entirely.
The Baby Who Inspired California’s Loud Streaming Ads Law
The legislation has an unusually personal origin story. According to the Desert Sun, Baby Samantha, the daughter of Zach Keller, a member of Senator Thomas Umberg’s staff, was startled awake by a loud streaming commercial as her parents, Zach and Rachel Keller, had settled down to watch a show.
The incident made its way into the Senate chamber. Senator Umberg, a Democrat representing Santa Ana who chairs the Senate Judiciary Committee, said the bill was inspired by ‘every exhausted parent who’s finally gotten a baby to sleep, only to have a blaring streaming ad undo all that hard work.’
It is a retail-politics pitch, but the underlying frustration is genuine. Broadcast and cable commercials have been volume-capped in the United States since the CALM Act passed in 2010. Streaming, which now captures the bulk of American television viewing time, was never covered by that federal framework. SB 576 fills that gap, at least within California’s borders.
Compliance Questions and the Spread Beyond California
How the major platforms will actually implement the requirements is, for now, unclear. Streaming services have not disclosed technical plans for complying with California’s loud streaming ads rules, according to Ars Technica.
That silence matters partly because any fix is unlikely to stop at the state line. Deploying separate audio processing for California viewers would be technically awkward; a single national solution is the more practical path. That logic is reinforced by the legislative calendar: Illinois has passed its own version of the restriction, SB 2804, which takes effect on 1 January 2027.
Two states, on overlapping timelines, raise the cost of doing nothing. Other legislatures will be watching both the legal landscape and the industry’s response.
The industry, for its part, opposed the California bill. The Motion Picture Association of America and the Streaming Innovation Alliance argued that platforms were already working to address volume inconsistencies voluntarily, and raised the practical complexity of managing audio across a range of output devices: televisions, tablets, and phones each handle volume differently. Those objections did not carry the day in Sacramento.
Whether they will matter more in Springfield or other state capitals may depend on how smoothly California’s implementation goes. If streaming services absorb the change without incident, the case for staying voluntary weakens considerably. If the technical challenges prove real, the industry will have the evidence it needs to push back on the next wave of state bills.
The first meaningful test arrives this week.
