California is introducing a new standard for streaming platforms: starting July 1, ads shown on services must not play louder than the content they accompany. The rule brings streaming closer to the volume limits already in place for broadcast and cable television commercials.
The change is expected to affect major streaming services operating in the state, although companies have not yet detailed exactly how they will adjust their ad systems. Because streaming platforms serve viewers across different devices, from TVs to phones and tablets, the update may encourage broader technical refinements in ad delivery.
The law was approved in 2025 and was backed by California State Senator Thomas Umberg, who framed it as a practical response to a familiar household moment: a quiet viewing session interrupted by an overly loud commercial. Industry groups had raised concerns about implementation, but the new rule now sets a clear benchmark for ad volume.
For now, the measure applies in California, yet it may influence how streaming advertising is managed in other markets as similar proposals move forward elsewhere. In the near future, quieter ad experiences could become a new standard for digital entertainment.
