Three major tech companies - Meta, TikTok, and Google's YouTube - are facing a landmark trial in Los Angeles this week over claims that their platforms deliberately harm children and drive online addiction. The case, brought by a 19-year-old plaintiff, could set a precedent for thousands of similar lawsuits against social media firms. The tech giants dispute the allegations, citing safeguards they've added, but executives like Meta's Mark Zuckerberg are expected to testify.

Why it matters

This trial could have profound effects on how tech companies handle children using their platforms, potentially sidestepping legal shields like the First Amendment and Section 230. It's the first in a wave of cases seeking to hold social media firms responsible for the youth mental health crisis.

The details

The lawsuit claims the tech firms deliberately designed their products to be more addictive to children in order to boost advertising revenue, borrowing tactics from the gambling and tobacco industries. The 19-year-old plaintiff, identified as KGM, alleges her early use of social media caused addiction, depression, and suicidal thoughts. Jury selection is expected to take at least a few days, with the full trial lasting 6-8 weeks.

  • The trial is set to begin this week in Los Angeles.
  • A federal trial is also scheduled to begin in June in Oakland, California, representing school districts suing social media platforms.
  • More than 40 state attorneys general have filed lawsuits against Meta over youth mental health harms.
