Existing law generally regulates social media platforms, including, among other laws, the Protecting Our Kids from Social Media Addiction Act that prohibits an operator of an addictive internet-based service or application, including a social media platform, from providing an addictive feed, as defined, to a minor user, except as prescribed. This bill would enact the Social Media Warning Law that would require a covered platform, as defined, to display a certain black box warning to certain users each day the user initially accesses the social media platform, again after 3 hours of cumulative active use, and thereafter at least once per hour of cumulative active use, as prescribed. This bill would specify that its provisions shall not be interpreted to serve as the basis for a private right of action, as specified. The bill would make its provisions operative on January 1, 2027, and would declare these provisions severable.
