What was the case against Meta?published at 14:36 BST
Meta's settlement ends a trial that began in Oakland, California, just over a week ago, and was due to last for six weeks.
It stemmed from a lawsuit filed in 2023 by 29 US states, including California and New York, which claimed numerous violations of federal and state privacy laws for children.
That includes breaches of the federal Children's Online Privacy Protection Act - intended to protect children under 13 years old from being targeted by businesses operating online.
The states allege Meta designed Facebook and Instagram to be addictive to children and teens, with features on the apps (such as video autoplay and Instagram Stories) made to keep them on there for as long as possible.
They claim Meta makes it difficult for young people to use the platform less - through functions like frequent notifications intended to get young people back on the apps.
The states allege the company has misled consumers about the safety of the platforms for young users.
Meta is also accused of improperly collecting and using children’s personal data while they used the company’s platforms.
Meta has consistently denied such claims.
