NetChoice sues Virginia to block its one-hour social media limit for kids

The tech industry trade group NetChoice is suing Virginia over a new law that will restrict minors from using social media for more than one hour per day. The lawsuit, filed on Monday, asks the court to block the law over claims it violates the First Amendment by putting “unlawful barriers on how and when all Virginians can access free speech online.”

Virginia Governor Glenn Youngkin signed the social media bill (SB 854) into law in May, and it’s set to go into effect on January 1st, 2026. Under the law, social media platforms will have to prevent kids under 16 from using the sites for more than one hour every day unless they receive permission from a parent.
