Mark Zuckerberg, co-founder of Facebook and CEO of Meta Platforms, has arrived in a California court to testify in a pivotal legal case. The trial centers on allegations that social media, including Meta's platforms like Instagram and WhatsApp, is addictive to children.

This marks Zuckerberg's first appearance before a jury in a case representing thousands of similar lawsuits against social media giants. Lawyers for Meta argue that the plaintiff, identified as K.G.M., suffered harm from external factors, not from her use of Instagram. The trial, which also names Google's YouTube as a defendant, is being closely monitored for its potential impact on the tech industry.
TikTok and Snapchat had previously settled with the plaintiffs before the trial began. K.G.M.'s legal team contends that social media firms deliberately designed their platforms to addict young users, despite awareness of mental health risks. Zuckerberg is expected to address questions regarding Instagram's design and its features aimed at retaining user engagement. Meta's reliance on advertising revenue, driven by user time spent on its platforms, is also a key focus.
The trial is anticipated to last several weeks and may include testimony from former Meta employees. The case is one of numerous lawsuits filed by families, state prosecutors, and school districts across the U.S. These suits accuse platforms like Meta, TikTok, and YouTube of fostering addictive behaviors that have harmed children. Some legal actions seek immediate platform changes, such as requiring Meta to remove accounts belonging to users under 13. Globally, governments are increasingly considering restrictions on youth social media use, with countries like Australia already implementing bans for those under 16.
