YouTube has filed an appeal in Los Angeles County Superior Court challenging a verdict that found the platform negligent in causing social media addiction among a young user, Kaley KGM, and that the company designed features to keep users engaged. Meta, the other defendant, filed a separate appeal shortly afterward, as both sides pursue post-trial motions following a jury award of $3 million in compensatory damages and a recommendation of $3 million in punitive damages. Lawyers for YouTube indicated that arguments will be detailed in subsequent filings, with YouTube contending its service is not a traditional social media platform. The case centered on design choices like autoplay and notifications, and questions over whether evidence encroached on legal protections under Section 230 of the Communications Decency Act. Both YouTube and Meta had sought new trials, but the trial judge denied those motions in June, cementing the current post-trial appeal process. Analysts and observers are watching how this landmark case could reshape platform design, liability standards, and regulatory considerations for tech companies.
