A California jury has delivered a groundbreaking verdict in the ongoing legal battle over social media addiction, holding Meta and YouTube liable for $3 million in damages to a woman who claimed the platforms caused significant harm through their algorithmic design and content delivery systems.

The landmark ruling represents the first successful case in what legal experts describe as a new frontier of technology litigation, where platforms are being held directly accountable for the psychological effects of their products on users. The case centered on allegations that both companies designed their algorithms to maximize user engagement in ways that proved harmful to mental health and well-being.
