The California streaming ad law known as SB 576 takes effect on 1 July, making it illegal for streaming services to run advertisements louder than the video content they accompany. The streaming industry, for its part, has said very little about how it plans to comply.
Governor Gavin Newsom signed the bill on 6 October 2025, describing it as ‘dialing down this inconvenience across streaming platforms, which had previously not been subject to commercial volume regulations passed by Congress in 2010.’ That 2010 federal law already covers broadcast and cable TV; streaming simply slipped through the gap for fifteen years.
What the California Streaming Ad Law Actually Requires
The compliance ask is not trivial. Trade publication TV Tech reported in December 2025 that, to meet the law’s requirements, streaming providers will need to integrate ‘file-based and, in some cases, real-time processing and loudness control into their server-side commercial insertion workflow, just as they currently do for their primary programming,’ according to Ars Technica.
That is a meaningful engineering lift, and it sits at the heart of the industry’s objection to the bill. Groups including the Motion Picture Association of America and the Streaming Innovation Alliance argued in a state Assembly analysis from September 2025 that ‘many’ services were already trying to manage ‘loudness of advertisements that come from server-side ad insertion that may be inconsistent with the loudness of the programs.’ In other words: we know, we’re working on it, please don’t legislate.
A second complaint, reported by BBC News, was that streaming platforms do not control the volume settings on the devices their content reaches (televisions, tablets, phones) unlike broadcast and cable providers who operate within a more controlled delivery chain. Fair point, as far as it goes. It does not, however, explain why the ads so reliably arrive louder than everything else.
A Baby, a Blaring Ad, and a Bill That Spread
State Senator Thomas Umberg said SB 576 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.’ The Desert Sun puts a more specific face on it: the infant in question is Samantha, daughter of Zach and Rachel Keller, whose father works for Senator Umberg. One loud commercial, one very awake baby, one piece of legislation.
The FCC had been tracking the frustration for years before California acted. According to Gigazine, the commission logged approximately 750 complaints about streaming ad volume in 2022, approximately 825 in 2023, and at least 1,700 by 2025. The trajectory makes the case for the law fairly neatly.
California will not be alone for long. Illinois Senate Bill 3222, sponsored by State Senator Doris Turner, passed the Illinois legislature in June 2026 and is scheduled to take effect on 1 July 2027. Given that California is home to the headquarters of Netflix and Hulu, and that Amazon produces a significant portion of its Prime Video content there, any compliance infrastructure built for the Golden State is likely to be deployed more broadly rather than geo-fenced at the border.
One thing SB 576 does not do: give viewers any legal recourse of their own. The law explicitly creates no private right of action, according to Baller Alert, so individual Californians cannot sue a streamer over a loud commercial. Enforcement sits with state regulators, not plaintiffs’ lawyers.
The streaming industry’s silence on implementation details is either confidence or procrastination. With Illinois watching and other states presumably taking notes, the calculation on waiting it out is getting harder by the quarter.
