Social Media’s Big Tobacco Moment?

Meta’s Mark Zuckerberg testified before a jury over claims social media harms young users. The outcome could influence more than 1,500 similar lawsuits.

Big Tech may be approaching what some legal experts call its “Big Tobacco moment.” In Los Angeles, Zuckerberg testified in a case alleging Meta and YouTube designed addictive platforms that harmed a young user’s mental health, claims both companies deny.

Internal documents shown in court suggest Meta knew preteens used its apps and aimed to maximize time spent scrolling. The company argues the materials are outdated and selectively presented, while maintaining there is no conclusive evidence linking social media to addiction.

Kaley’s lawsuit is viewed as a bellwether for more than 1,500 related cases. Her legal team is pursuing a novel strategy, focusing on product design rather than user-generated content, potentially sidestepping traditional Section 230 defenses.

“I think there’s a lot of parallels in that the outcome (in the social media trials) very much may change behavior in terms of how people approach social media,” he said.

Why This Matters

  • Legal experts say the case could shape how courts evaluate platform design and youth safety.
  • A plaintiff victory could increase financial exposure and pressure companies to adjust features.
  • Multiple defense wins could weaken the value of pending lawsuits.

What’s Next

  • Meta and YouTube’s legal teams are expected to present fuller arguments in the coming weeks.
  • Additional bellwether trials are likely to follow with varying outcomes.
  • The verdict may influence settlement strategies and broader regulatory debate.
