The Reuters/Ipsos poll, which was conducted over the six days ending Aug. 3, comes as companies like Meta Platforms and Google's YouTube face mounting legal pressure over their treatment of young users. A trial is expected to begin on Wednesday over allegations by state prosecutors that Meta designed its products to addict young users.

Meta, which denies the allegations, says it could face up to $1.4 trillion in penalties if the states prevail. A New Mexico state court on Thursday separately ordered Meta to pay $567 million into a teen mental health fund and change how its platforms function for young users, after finding the company is to blame for harming children's wellbeing.

Tech companies are also under increasing scrutiny by lawmakers across the U.S. for their effect on youth. More than a dozen states have passed laws regulating minors' social media access, saying it is needed to bolster their safety online. NetChoice, a trade group backed by social media giants such as Meta, TikTok and Snap, has sued to stop laws requiring apps verify the ages of their users. It argues such laws violate free speech protections.
