Social media companies Meta and YouTube lost a landmark lawsuit over platform addiction that harmed a user's mental health, with the jury awarding millions in damages in a case that may set precedent for similar claims.

On Wednesday, an LA jury found Meta and YouTube liable for designing addictive platforms that harmed 20-year-old Kaley's mental health, awarding $3 million in compensation and $3 million in punitive damages, while TikTok and Snap settled before trial but face upcoming bellwether trials.
