California law targeting loud streaming ads takes effect on July 1

A California law taking effect July 1 bans streaming services from running ads that are louder than the video content they accompany. Similar rules already apply to broadcast and cable TV, while Illinois is set to enact a comparable streaming ad volume law next year.

The law may push platforms to standardize ad volume controls nationwide rather than build state-specific compliance systems. It also signals growing regulatory scrutiny of streaming services as they inherit consumer protection rules long applied to traditional TV.
