California law requiring streaming ads to match content volume takes effect July 1
Tags Consumer · Policy
A new California law targeting excessively loud streaming advertisements takes effect on July 1, 2026, requiring that ad volume not exceed the average volume of the content they accompany. The legislation, introduced by Assemblymember Thomas Umberg, extends the spirit of the federal CALM Act (which covered broadcast TV) to streaming platforms. Non-compliant platforms face potential fines. The law applies to all streaming services accessible in California, effectively setting a national standard given the size of the California market and the impracticality of maintaining separate audio profiles by state.
Technical significance
The law forces streaming platforms to implement real-time loudness normalization across their ad insertion pipelines, which requires audio processing infrastructure changes. Because California represents the largest US market, platforms will likely implement the change globally rather than maintain separate audio profiles, making this a de facto national standard for streaming audio normalization.
