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.

California Gov. Gavin Newsom signed a bill on Friday that could entirely reshape how kids in the state use social media. Among the potential changes: A requirement that could effectively reshape the TikTok "For You Page" as minors now know it.

New York Gov. Kathy Hochul signed two bills in June restricting digital platforms' algorithms and use of children's data. Social media platforms will be required to display content chronologically by default for kids under 18. And websites would be banned from collecting or sharing the personal data of users under 18 without consent.
