A Los Angeles jury on Wednesday found Meta and Google-owned YouTube liable in a first-of-its-kind social media addiction case that accused the companies of designing products that harmed a young user’s mental health. The verdict is being watched closely because it could shape thousands of similar lawsuits now moving through the courts.
The case was brought by a 20-year-old plaintiff identified in court as KGM, who said she began using YouTube at age 6 and Instagram at age 9 and became compulsively attached to the platforms as a child. Her lawyers argued that features such as infinite scroll, autoplay and notifications were designed to keep users engaged and should have been disclosed as risky, especially for minors.
Jurors found that Meta and YouTube were negligent in the design or operation of their platforms and that the negligence was a substantial factor in causing harm. AP reported that jurors awarded $3 million in damages and later recommended an additional $3 million in punitive damages after finding malice, oppression or fraud.
Reuters described the Los Angeles trial as a bellwether for thousands of similar lawsuits consolidated in California state courts, and AP said the ruling could influence the outcome of other cases accusing social media companies of deliberately causing harm.
The trial also tested a narrower legal strategy. Plaintiffs focused on product design rather than the content on the platforms, a distinction that matters because U.S. law broadly shields social media companies from liability for content posted by users. AP reported that jurors were told not to consider the content KGM viewed because of those legal protections.
Meta and Google said they disagree with the verdict and plan to appeal. Reuters reported that both companies maintained the case did not prove their platforms caused the plaintiff’s injuries, while AP quoted Meta saying teen mental health is complex and cannot be linked to a single app, and YouTube saying it is a responsibly built streaming platform rather than a social media site.
The trial is part of a wider legal and political shift around youth online safety. Reuters reported that at least 20 states enacted laws last year on social media use by children, and that another social media addiction case involving states and school districts is expected to go to trial later this year.
For now, the verdict does not force immediate changes to either company’s platforms. But it does give plaintiffs in related cases a significant courtroom result to point to, and it puts new pressure on major platforms to defend their design choices in legal terms rather than only in public relations terms. That is the central significance of this ruling.
