Children's Online Privacy Protection Act (COPPA, 1998)
Congress enacted the first federal law restricting online data collection from children under 13, requiring parental consent and creating the under-13 age gate that still shapes the web.
The Federal Trade Commission enforced COPPA through numerous consent decrees, making age-gated data practices a national baseline.
Demonstrated that a single strong law can become a de facto national standard through industry compliance.
California's new rules aim to replicate that playbook: a robust state law that platforms adopt nationwide rather than build state-specific versions.
