Landmark Trial to Test Claims That Instagram and YouTube Addicted and Harmed a Teen User

Landmark Trial to Test Claims That Instagram and YouTube Addicted and Harmed a Teen User

A landmark social media trial is set to begin in Los Angeles, where lawyers for a now 20-year-old woman will argue that Instagram and YouTube intentionally designed addictive features that harmed her mental health during her teenage years.

The plaintiff, identified only by her initials KGM, alleges that prolonged use of the platforms contributed to anxiety, body dysmorphia, and suicidal thoughts. The lawsuit claims the companies prioritized engagement over safety, creating design features that encouraged compulsive use among young users.

The case, filed against Meta, the parent company of Instagram, and YouTube, is the first of roughly 1,500 similar lawsuits expected to go to trial across the country. Legal experts say the outcome could influence how the remaining cases are resolved and could expose tech companies to billions of dollars in potential damages.

During jury selection, KGM’s attorney argued that features such as endless scrolling, frequent notifications, and appearance-altering filters were intentionally designed to keep young users online for extended periods. According to court statements, KGM began using YouTube at age six and Instagram at age nine, at times spending several hours a day on each platform.

The lawsuit also alleges that KGM experienced bullying and sextortion on Instagram, further worsening her mental health. Sextortion involves threats to share explicit images unless additional content or money is provided.

Attorneys for Meta and YouTube are expected to argue that KGM’s mental health challenges stemmed from a difficult family environment rather than social media use. They have indicated they will emphasize parental responsibility and existing safety tools offered by the platforms.

Executives including Meta CEO Mark Zuckerberg, Instagram CEO Adam Mosseri, and YouTube CEO Neal Mohan are expected to testify in the coming weeks. Snap and TikTok were also named in the lawsuit but reached settlements before the trial began.

Supporters of the lawsuit, including parents and online safety advocates, say the case represents a critical test of accountability for the tech industry. The companies maintain that their platforms are not harmful and point to safeguards such as parental controls, usage reminders, and content restrictions.

The trial is being overseen by a Los Angeles Superior Court judge, who has instructed jurors to continue their normal social media use but avoid seeking out any information related to the case.
