California Streaming Law Brings Broadcast Ad-Volume Rules Online

California's SB 576, effective July 1, 2026, requires streaming platforms to enforce federal CALM loudness standards—the same rules for broadcast and cable since 2012. Ads must match program content volume, measured by integrated loudness rather than peak levels. Platforms lacking normalization pipelines face significant ad-workflow changes. Enforcement runs through state attorneys general and consumer litigation, not the FCC.
