Meta CEO and Chairman Mark Zuckerberg arrives at Los Angeles Superior Court ahead of the social media trial tasked to determine whether social media giants deliberately designed their platforms to be addictive to children, in Los Angeles, on Feb. 18, 2026.
Meta CEO Mark Zuckerberg walked into Los Angeles Superior Court just before noon ET Wednesday to testify in a landmark trial about social media and safety that's being likened to the industry's "Big Tobacco" moment.
Several members of the team escorting him into the building were pictured wearing the Meta Ray-Ban artificial intelligence glasses.
The Ray-Ban logo was visible on the side, along with the small cameras in the corners.
Recording is not allowed in the court room.
The trial, which began in late January, centers on a young woman who alleged that she became addicted to social media and video streaming apps like Instagram and YouTube .
Lawyers representing the plaintiff contend that Meta, YouTube, TikTok and Snap misled the public about the safety of their services and knew that the design of their apps and certain features caused mental health harms to young users.
Snap and TikTok settled with the plaintiff involved in the case before the trial began.
