California Gov. Gavin Newsom on Friday signed a bill that aims to reduce social media use among children, the latest state effort to regulate the medium over increasing concerns that heavy use is damaging to young people.

Gov. Gavin Newsom signed the bill on Friday. It also prohibits kids getting social media notifications late at night or during school hours.

California will, starting in 2027, prohibit social media platforms from deliberately delivering addictive feeds to minors without parental consent as part of a new law. The big picture: States and cities have been grappling with how to limit what health experts deem to be harmful effects of social media on children and teens.
