California law limiting loud streaming ads takes effect July 1

A California law restricting streaming services from showing ads 'louder than the video content' that they accompany is set to take effect on July 1. Existing legislation already imposes similar volume restrictions on broadcast and cable TV commercials. Ars Technica notes that streaming services have not shared additional details about how they plan to comply with the law.

While the volume limitations only apply to California for now, it seems likely that any relevant changes would be deployed more broadly, especially with a similar bill set to take effect in Illinois next year. When the law was passed in 2025, its sponsor, State Senator Thomas Umberg, said it 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.' Industry groups including the Motion Picture Association of America and the Streaming Innovation Alliance opposed the bill, claiming streamers were already working to address the issue, and noting that they have to deal with a variety of output devices, including TVs, tablets, and phones. Why this matters: The new California law could have a significant impact on the streaming industry, particularly in how ads are delivered to users.

For developers and businesses, this means reevaluating their ad delivery systems to ensure compliance with the new regulations. For consumers, this could lead to a more pleasant viewing experience, with fewer jarring loud ads. However, questions remain about how streaming services will implement these changes, and whether they will adopt a uniform approach across different platforms.

The fact that similar bills are pending in other states, such as Illinois, suggests that this could become a broader trend in the industry, and one that companies will need to adapt to in order to avoid a patchwork of different regulations.
