California: US federal regulators are fining Facebook five billion US dollars for privacy violations and instituting new oversight and restrictions on its business.
The fine is the largest the Federal Trade Commission has levied on a tech company, although it won't much dent a company that had nearly 56 billion US dollars in revenue last year.
As part of the agency's settlement with Facebook, CEO Mark Zuckerberg will have to personally certify his company's compliance with its privacy programs.
The FTC said that false certifications could expose him to civil or criminal penalties.
