Instagram Head Testifies in Meta Child Social Media Trial
Adam Mosseri, Instagram’s leader, testified in a major court case about children using social media.
The case was brought by 29 states against Meta, which owns Instagram and Facebook.
Four states say Meta designed the apps to keep young people using them too much.
They say this may have contributed to anxiety, depression, and suicide.
The states also say Meta collected information from children under 13 improperly.
Meta says it did not try to addict children and that its research does not show a clear connection between social media and poor well-being.
Another Instagram executive said teenagers saw more harmful content than adults in one company presentation.
A judge will ultimately decide whether Meta broke the law and what penalties or changes may be required.
The trial is expected to continue through much of September.
Adam Mosseri testified as a central witness in a lawsuit brought by 29 U.S. states against Meta.
Four states accuse Meta of designing Instagram and Facebook to hook young users and harm their safety.
All 29 states allege Meta improperly collected and used data from children under 13.
Meta denies seeking to addict children and says its research found no clear link to adolescent social-media use and poor well-being.
The trial may result in nearly $200 billion in penalties, with Judge Yvonne Gonzalez Rogers to decide Meta’s liability.
