Streaming services' obnoxiously loud ads become illegal on July 1 in California
California Bans Blasting Streaming Ads Starting July 1
Starting July 1, streaming platforms in California will be legally prohibited from playing commercials that are louder than the actual program content.
The Legal Framework: SB 576
As reported by The Hollywood Reporter, Governor Gavin Newsom signed SB 576 in October 2025. This legislation specifically forbids any video streaming service within the state from transmitting "audio of commercial advertisements louder than the video content the advertisements accompany."
This move aims to create a standard of parity between the digital streaming world and traditional media.
Comparison of Audio Regulations
| Medium | Governing Regulation | Requirement |
|---|---|---|
| Broadcast, Cable, Satellite | CALM Act (FCC) | Ads must be at the same average volume as the program. |
| Streaming Services | SB 576 (California) | Ads cannot be louder than the accompanying content. |
Geographic Reach and Implementation
While the law is specific to California, the industry's response remains uncertain. It is currently unknown if providers will implement these volume caps exclusively for California residents or apply them to all US streams.
Compliance Timeline:
- California: Effective July 1, 2026
- Illinois: Effective July 1, 2027 (per a recently passed bill)
Streaming services can ignore these rules Streaming services must now integrate loudness controls.
Industry Pushback and Technical Hurdles
The legislation was not without opposition. Major industry groups, including the Motion Picture Association (representing Netflix, Disney, Amazon Prime Video, and Paramount) and the Streaming Innovation Alliance (representing Netflix, Disney, Peacock, and Pluto TV), fought the bill.
"Many streaming services were already trying to manage the loudness of advertisements that come from server-side ad insertion that may be inconsistent with the loudness of the programs." — State Assembly Analysis (Sept 2025)
The Technical Challenge: Server-Side Ad Insertion (SSAI)
The primary issue stems from how ads are delivered. Because different companies use various encoding pipelines, the resulting audio levels can vary wildly.
Furthermore, services must ensure consistency across a fragmented ecosystem of hardware:
- Smart TVs
- Tablets
- Mobile Phones
According to TV Tech, providers will need to implement a more rigorous workflow:

A Persistent Problem
Even with the existing CALM Act for traditional TV, viewers remain frustrated. The FCC has tracked a steady rise in complaints regarding loud commercials:
