What Happened
Mark Zuckerberg appeared in Los Angeles County Superior Court to face questions about whether his company intentionally designed Instagram to be addictive. The trial centers on claims by KGM (also known as Kaley), now 20, who alleges that compulsive social media use beginning in childhood contributed to depression, anxiety, body dysmorphia, and suicidal thoughts.
The plaintiff’s attorney, Mark Lanier, told the jury the case was “as easy as ABC,” which he said stood for “addicting the brains of children.” Lanier argued that “these companies built machines designed to addict the brains of children. And they did it on purpose.”
Zuckerberg’s testimony marks the first time the Meta CEO has answered before a jury about long-standing claims that his platforms harmed young people. He entered the courthouse around 8:30 a.m. local time past a crowd of parents, media, and other trial attendees.
Why It Matters
This trial represents a pivotal legal test that could reshape the entire social media industry. The central question is whether platforms like Instagram and YouTube constitute “defective products” engineered to exploit vulnerabilities in developing brains.
The outcome could impact approximately 1,600 other pending social media addiction cases from families and school districts across the country. Legal experts say a plaintiff victory could weaken the broad liability protections tech companies have relied on under Section 230 of the Communications Decency Act.
For millions of parents whose children use social media, the trial addresses growing concerns about platforms’ impact on youth mental health amid rising rates of teen anxiety and depression.
Background
The lawsuit points to internal company documents showing how social media platforms deliberately designed addictive features including infinite scroll, auto-play videos, likes, beauty filters, and push notifications to keep users engaged.
KGM’s case alleges she experienced bullying and sextortion on Instagram after beginning to use social media as a young child. Her lawyers argue these platforms specifically target young users’ psychological vulnerabilities to maximize engagement time.
Both TikTok and Snap settled their cases before trial, leaving Meta and Google as the remaining defendants. Instagram head Adam Mosseri testified one week before Zuckerberg, defending the platform by arguing there’s a difference between “clinical addiction and problematic use.”
The legal strategy mirrors tobacco industry litigation from the 1990s, where internal documents revealed companies knew their products were harmful while publicly denying health risks.
What’s Next
The jury of 12 needs at least 9 members to agree on a verdict. A decision favoring the plaintiff could result in monetary damages and force significant changes to how social media platforms operate, particularly regarding features targeting young users.
Meta has defended its practices, with a spokesperson saying the company “strongly disagrees” with the allegations and pointing to safety features like parental oversight tools and “teen accounts” with default privacy settings for users under 18.
Separate child safety lawsuits against Meta are proceeding in New Mexico, while additional school district cases modeled after tobacco litigation are expected to go to trial later this year.
The trial continues with bereaved parents filling the courtroom, holding photos of children who died after encountering harm on social media platforms. The proceedings are being closely watched by tech industry observers, child safety advocates, and families worldwide as a potential turning point in social media accountability.
