A major privacy bill signed into law in California on Thursday is poised to reshape how Silicon Valley does business. When the law goes into effect, companies will face the country's toughest privacy requirements, including stopping the collection and sale of personal data upon request from consumers. 

The bill flew through the California statehouse Thursday, with the state's Senate and Assembly each voting to pass it unanimously. Gov. Jerry Brown then signed it within a matter of hours. The rush to pass the bill comes courtesy of an even stricter voter initiative that would've appeared on California ballots this November if lawmakers hadn't gotten the bill through by 5 p.m. PT Thursday.
