The news: A Los Angeles Jury found on Wednesday that Meta and Google were negligent in failing to warn users, particularly young audiences, about the risks tied to their platforms—a landmark decision with broad implications for social media.

Meta is liable for 70% of the $3 million in compensatory damages assessed; YouTube is responsible for the additional 30%. The plaintiff alleged that apps including YouTube and Instagram caused social media addiction as a child and played a "substantial factor” in causing mental health damage. TikTok and Snapchat settled earlier in the case against Meta and YouTube, but are still facing other legal proceedings regarding mental health impacts.

Zooming out: Dubbed by many as social media’s “Big Tobacco” moment, the trial could mark a turning point in the global, yearslong debate over how social media harms young users.

• Several countries are implementing or considering legislation that would ban social media for minors. Australia led the pack with a landmark December 2025 decision to ban social media access for those under 16; India, the United Kingdom, Greece, and others are considering similar actions.
• Platforms are responding through intensified age verification protocols. Roblox requires all users to verify age via selfie or ID; TikTok has strict requirements in Europe to remove accounts under 13; YouTube already has an AI-powered age verification system that estimates user ages.

These actions have widespread support: 74% of US adults support federal regulations that would prevent the collection of children’s personal data; 71% support platforms requiring parental consent to set up an account; 61% support age verification for all users, per CivicScience.

Looking ahead: The trial could indicate what is to come for age-related social media restrictions—and will likely open the floodgates for other private litigation that will determine the full scope of Meta and Google’s exposure.

It also raises the pressure on platforms to do more than defend their safety practices in court, pushing them to proactively strengthen youth protections, transparency, and parental controls. As similar cases move forward, the verdict may give lawmakers and regulators momentum to pursue stricter rules around platform design, duty of care, and age-based access.

Implications for marketers: The decision doesn’t mean Meta and YouTube are less viable ad channels given their scale—but it does raise questions on how marketers will approach youth-centric media plans in the future. The risk of being associated with platforms causing measurable harm to minors presents reputational and governance concerns; marketers will likely have to exercise increased caution with what content they promote to platforms with large youth audiences.

Media diversification at scale will become increasingly important. Marketers must prepare to shift to strategies that balance reach across youth-safe channels to avoid the legal shock that can come when relying on any single platform.
