National Do Not Call Registry opens (2003)
The Federal Trade Commission opened a single registry where people could block most telemarketing calls with one signup. By late October 2003 it held 53.7 million phone numbers. Telemarketers had to scrub their lists against it regularly or face fines of up to $11,000 per call.
Tens of millions registered within months, and telemarketers challenged the registry in court before it survived and took effect.
The registry became a lasting model for one-stop, government-run opt-out systems that put the burden on companies to check a central list.
DROP applies the same design to data deletion: one government list, and companies must check it on a fixed schedule or pay per violation.
