Mark Zuckerberg Testifies in Landmark Trial Over Social Media’s Impact on Kids

Meta CEO Mark Zuckerberg is testifying today in a high-profile U.S. trial examining the effects of social media on children. The case focuses on claims that platforms like Instagram were designed to engage young users in ways that can harm mental health.

A 20-year-old plaintiff alleges that social media worsened her depression and suicidal thoughts, while lawyers argue companies employed casino-style design tactics to keep kids scrolling. TikTok and Snap settled before trial, leaving Meta and YouTube to face court scrutiny.

Zuckerberg is expected to answer questions regarding algorithms and potentially addictive features. Instagram’s chief has already testified, denying that the platform is “clinically addictive,” though internal research reportedly acknowledges some harm to users’ body image. Meta maintains it has done nothing wrong and emphasizes its commitment to protecting young users. Experts warn that the outcome could set a precedent for thousands of future lawsuits and reshape legal protections for Big Tech.
