Meta, the owner of Facebook, Instagram and WhatsApp, has gone on trial, accused of breaking state and federal laws around child privacy. The trial is expected to last around six weeks.
The lawsuit has been filed by 29 US states, representing more than two thirds of the country's population. This is the largest of a number of lawsuits against Meta relating to child safety.
This trial may require a payout of $200 billion in damages from Meta if they lose the case and the court could also force the company to make changes to its products.
Meta denies the allegations saying that it removes child accounts and that it is taking steps to improve teenagers' wellbeing on their platforms.
