California’s War on Blaring Streaming Ads Begins July 1

The End of the “Jump Scare” Commercial
For years, millions of viewers have experienced a jarring phenomenon: settling into a quiet movie or a whispered dialogue scene, only to be jolted awake by a streaming commercial that feels ten times louder than the preceding content. Starting Wednesday, July 1, that experience may become illegal in California.
A new state law takes effect this week, explicitly banning streaming services from delivering advertisements that are louder than the video content they accompany. While broadcast and cable television have been subject to similar volume restrictions for years—largely thanks to the CALM Act (Commercial Advertisement Loudness Mitigation Act) of 2010—the digital streaming frontier has remained a wild west of unpredictable audio levels.
Closing the Digital Loophole
The legislation targets the specific discrepancy between a show’s dynamic range and the compressed, high-volume nature of modern digital advertising. The catalyst for the bill was not just consumer annoyance, but a quality-of-life issue for millions. State Senator Thomas Umberg, the bill’s sponsor, noted that the legislation was inspired by the collective frustration of parents whose sleeping infants are routinely awakened by a sudden blast of high-decibel promotional material.
Historically, streaming platforms have operated under a different set of rules than linear TV. In traditional broadcasting, loudness standards are strictly enforced via hardware and network-level processing. In the streaming ecosystem, the volume is often a confluence of the ad creator’s mastering, the platform’s player settings, and the user’s hardware. By codifying this restriction, California is effectively forcing streaming giants to implement more aggressive loudness normalization—a process that ensures a consistent perceived volume across different pieces of audio content.
Industry Pushback and Technical Hurdles
The transition hasn’t been without friction. Major industry advocacy groups, including the Motion Picture Association of America and the Streaming Innovation Alliance, voiced opposition during the legislative process. Their primary argument centered on the technical complexity of the streaming environment.
Unlike a cable box, which provides a consistent output, streaming content is consumed across a fragmented array of devices. An ad played on a high-end OLED TV with a surround sound system behaves differently than the same ad played on a budget Android tablet or a smartphone. Industry representatives argued that streamers were already iterating on these issues and that a rigid legal mandate could lead to inconsistent audio experiences across different hardware ecosystems.
A Potential National Domino Effect
While the law currently only applies to users within California borders, the practical reality of software deployment suggests a broader impact. It is technically inefficient for companies like Netflix, Disney+, or Hulu to maintain separate audio-level processing pipelines specifically for California IP addresses. Most likely, streamers will apply a global volume normalization update to ensure compliance, effectively extending California’s consumer protections to users nationwide.
This move is likely the first of many. Illinois is already preparing to implement a similar bill next year, suggesting a growing regulatory appetite for cleaning up the digital ad experience. As streaming services continue to pivot toward ad-supported tiers to combat churn and increase Average Revenue Per User (ARPU), the tension between intrusive advertising and user experience is reaching a breaking point. California’s new law signals that the “anything goes” era of digital ad volume is coming to an end.
