A Los Angeles jury has found Meta Platforms Inc. and Alphabet Inc.’s Google liable for negligence in a landmark case alleging that their platforms contributed to mental health harms in a young user, marking a significant moment for the social media industry and its legal exposure.
The verdict, delivered Wednesday in Los Angeles Superior Court, awarded the plaintiff $3 million in compensatory damages, with Meta responsible for 70% and YouTube for the remaining 30%.
The case is widely viewed as a potential turning point, with experts likening it to a “Big Tobacco” moment for the technology sector.
Jury finds negligence in platform design
The case centered on claims brought by a 20-year-old woman identified as Kaley G.M., who alleged that prolonged exposure to platforms such as Instagram and YouTube from a young age led to severe mental health issues, including depression, anxiety, and body dysmorphia.
Jurors concluded that the companies’ negligence was a “substantial factor” in causing harm.
The trial examined whether features such as recommendation algorithms and auto-play functions contributed to addictive usage patterns and exacerbated psychological distress.
The plaintiff testified that she began using YouTube at age six and Instagram at nine, and experienced escalating mental health challenges tied to near-constant engagement with the apps.
In response to the ruling, a Meta spokesperson said: “We respectfully disagree with the verdict and are evaluating our legal options.”
Both Meta and YouTube denied the claims during the trial, arguing that they had implemented safety features and that the plaintiff’s issues stemmed from personal and family circumstances rather than platform design.
Broader legal risks for tech firms
The verdict underscores growing legal risks for major technology companies as thousands of similar lawsuits progress through courts across the United States.
This case was selected as a bellwether under California’s coordinated legal proceedings, meaning its outcome could influence other related cases.
Although platforms such as TikTok and Snap were initially included, they reached settlements before the trial began.
A separate case in New Mexico further added to the pressure.
Jurors there found Meta had violated state unfair practices laws and ordered the company to pay $375 million in damages, a decision the company has said it will appeal.
Legal strategies in these cases have increasingly focused on alleged design flaws rather than user-generated content, in an effort to bypass protections under Section 230, which typically shields platforms from liability for third-party content.
Industry faces “Big Tobacco” moment
The Los Angeles trial featured testimony from senior executives, including Meta CEO Mark Zuckerberg, Instagram head Adam Mosseri, and YouTube engineering executive Cristos Goodrow.
Mosseri pushed back last month on the notion of social media addiction, characterizing it as “problematic” usage.
Zuckerberg’s testimony revealed internal discussions around user wellbeing, including outreach to Apple CEO Tim Cook on issues affecting teens.
Goodrow said in his testimony that YouTube was “not designed to maximize time.”
Despite these defenses, the jury’s decision highlights increasing scrutiny of how digital platforms are designed and their potential impact on users, particularly minors.
A federal trial involving similar claims from school districts and parents nationwide is set to begin later this year, suggesting that the legal and financial challenges facing the social media industry are far from over.
