Social media giant Meta is on trial over claims it deliberately designed its platforms to be addictive to young people

The four US states in court are seeking billions of dollars from Meta - they're acting on behalf of a group of 29 states that filed a lawsuit in 2023 arguing the company violated child privacy laws

A lawyer for California tells the court Meta's business model aims to "Hook the users; hold them for as long as they can; harvest their data; (and) hide the truth from the public"

Meta, which owns Facebook and Instagram, says it "strongly disagrees" with the allegations and evidence will show its "longstanding commitment to supporting young people"

The trial - taking place at a federal court in California - is expected to last six to eight weeks

Our North America technology correspondent writes it is "shoulder to shoulder" in the Oakland courtroom where the case is taking place
