Zuckerberg Faces Court Over Teen Social Media Addiction
Meta CEO Mark Zuckerberg testified in Los Angeles Superior Court in a landmark trial examining whether social media products are addictive and harmful to teens. Plaintiff KGM (also known as Kaley), a 20-year-old, sued four social platforms; TikTok and Snap settled before trial while YouTube and Meta are defending. Trial evidence included Meta research saying parental supervision often could not prevent compulsive use and that traumatized teens were more likely to overuse social apps, a 2015 email chain showing Zuckerberg pushed to increase time spent by 12%, and internal estimates that millions of under‑13 children had Instagram accounts. The jury outcome could prompt legal reforms, settlements and platform changes.
A high‑profile legal trial against a major platform (Meta) could drive regulatory changes, platform policy shifts (age verification, safety features) and potential settlements that affect user policies and business risk for ad-supported social platforms.

Instagram Chief Compares Social Media Addiction to Binge-Watching
Instagram head Adam Mosseri testified on Feb. 11, 2026, in a Los Angeles Superior Court trial alleging that major social platforms misled the public about safety and that design choices fostered harmful effects on young users. Mosseri said he differentiates between clinical addiction and problematic use, noting a casual remark that he was "addicted" to a Netflix show does not equal a medical diagnosis. The case targets Meta (Instagram), YouTube, TikTok and Snap; TikTok and Snap previously settled and are no longer involved. Trial exhibits included internal Meta emails debating whether to ban digital filters that might encourage plastic surgery; Mosseri said the company chose a focused ban on some filters and maintained that filters do not drive ad revenue. Plaintiff attorney Mark Lanier questioned executives about product decisions and risks to minors.
Instagram's Teen Targeting Under Fire in Lawsuit
During testimony in K.G.M. v. Platforms et al. in Los Angeles County Superior Court, internal documents and emails showed Instagram tracked increasing time‑spent milestones and highlighted a focus on tweens and teens. The evidence cited daily usage rising from 40 minutes per day in 2023 to 46 minutes per day in 2026. The 19‑year‑old plaintiff (K.G.M., “Kaley”) alleges social media use contributed to addiction and mental‑health harm. Snap and TikTok settled before trial; Meta and YouTube executives, including Meta CEO Mark Zuckerberg, provided testimony. Plaintiff lawyers point to internal goals such as “total teen time spent” and emails noting age requirements were hard to enforce. Meta disputes causation and says it has implemented teen protections and age‑collection changes over time.
Zuckerberg Faces Court in Landmark Social Media Safety Trial
Meta CEO Mark Zuckerberg testified Feb. 18, 2026 in a Los Angeles Superior Court trial that he reached out to Apple CEO Tim Cook to discuss the "wellbeing of teens and kids," referencing a February 2018 email exchange. The testimony was part of a broader defense effort to show Meta considered youth safety issues amid allegations that Instagram and other platforms design features that harm young users. Topics covered included Instagram's temporary ban and later lifting of cosmetic-surgery/beauty filters, internal disagreements among product leaders, reported internal goals to increase engagement time, and documents stating about 4 million U.S. users under 13 used the platform. The trial accuses Meta, YouTube and others of misleading the public about risks to young users; Meta denies the allegations. The session also featured courtroom limits on AI glasses and discussion of age verification responsibilities.
