Meta and YouTube Found Liable in Landmark Social Media Addiction Trial

A California jury on March 25 found Meta and YouTube liable on all counts in a landmark social media addiction case brought by a 20-year-old woman identified as KGM. The jury ruled that both companies negligently designed their platforms, knew their products were dangerous, failed to warn users of those risks, and caused substantial harm to the plaintiff. Meta was assigned 70% of liability and Google's YouTube 30%. The jury awarded $3 million in compensatory damages and $3 million in punitive damages, split between the two companies. Meta and YouTube said they plan to appeal. The legal strategy that made the verdict possible is the part that matters most. Plaintiff attorneys focused on platform design decisions rather than user-generated content, bypassing Section 230, the law that has shielded tech companies from content-related liability for decades. Internal Meta documents shown to the jury included one in which executives noted that 11-year-olds were four times as likely to return to Instagram compared to competing apps, and another that read "if we wanna win big with teens, we must bring them in as tweens." The jury deliberated for more than 40 hours after a seven-week trial. The day before the verdict, a separate New Mexico jury ordered Meta to pay $375 million for failing to protect children from sexual predators on its platforms. The $6 million award is small compared to Meta and Alphabet's balance sheets, but the legal precedent is not. More than 2,400 related cases are consolidated in California federal court, and the next federal bellwether trial is scheduled for June 2026. Legal experts are comparing the trajectory to the Big Tobacco litigation of the 1990s, where early verdicts led to industry-wide settlements worth hundreds of billions. Jonathan Haidt, author of The Anxious Generation, said to CNN: "You add it all up and it could be hundreds of billions of dollars." For digital agencies and social media marketers in Nigeria, this trial signals a shift in how platforms will be regulated globally. If courts continue ruling against platform design, you should expect algorithmic changes, feed restructuring, and tighter restrictions on how platforms target and retain younger users. The tools you use today are being challenged at their foundations. How platforms are built will change before how they are used does. That gap is where agencies need to stay sharp.
