Meta and Google-owned YouTube have been found liable for designing addictive products that harmed a young user, following a jury verdict in Los Angeles. The decision, delivered on Wednesday, marks the first time a social media case of this kind has proceeded to trial and resulted in a finding of liability against major technology companies.

A 12-person jury concluded that both companies were negligent and failed to provide adequate warnings about the potential risks associated with their platforms. The panel awarded the plaintiff, a 20-year-old woman identified in court as KGM, damages of $6m (£4.7m), assigning 70 per cent of responsibility to Meta and 30 per cent to YouTube.

The case centred on the design of platform features, including autoplay and infinitely scrollable feeds, which jurors found contributed to compulsive use. Both companies have said they intend to appeal the verdict.

Evidence Presented During the Trial

The six-week trial at Los Angeles superior court included testimony from company executives, expert witnesses and the plaintiff. KGM told the court she began using YouTube at the age of six and Instagram at nine, and linked her subsequent mental health difficulties to prolonged use of the platforms.

According to reporting by The Guardian, jurors were also shown internal materials and expert analysis examining how specific product features function. The evidence focused on whether these design elements encouraged extended engagement among younger users.

Legal Arguments on Product Design

Lawyers for the plaintiff argued that the platforms incorporated features intended to maximise user engagement, drawing comparisons with approaches previously used in other industries. They said tools such as autoplay and continuous scrolling increased the likelihood of repeated use.

To reach its verdict, the jury was asked whether the companies' conduct was a substantial factor in causing harm and whether they were aware of potential risks linked to product design. The panel returned a majority decision in favour of the plaintiff on all counts.

Company Response and Appeal Plans

Meta said it would appeal the decision, stating it 'respectfully disagrees with the verdict' and that 'teen mental health is profoundly complex and cannot be linked to a single app'. The company said it had introduced measures intended to support younger users.

YouTube also confirmed it would appeal. A spokesperson said the case 'misunderstands YouTube' and described the platform as 'a responsibly built streaming service'. Both companies have consistently denied wrongdoing.

Broader Legal and Industry Impact

The verdict represents a significant development in legal challenges facing social media companies, particularly those focused on platform design. While the appeals process is likely to take time, the case is expected to be closely monitored by regulators and industry stakeholders.

This case is part of a wider group of lawsuits in California involving more than 1,600 claimants, including families and school districts. TikTok and Snap, which were initially included, settled with the plaintiff before the trial began.

The Los Angeles case is the first of several 'bellwether' trials intended to test legal arguments and assess how juries respond to claims about platform design. Additional proceedings are expected in both state and federal courts in the coming months.

Further rulings may clarify how responsibility is assigned in cases involving digital platforms and user wellbeing, as similar claims continue to progress through the courts.
