Instagram chief Adam Mosseri is to be called to testify Wednesday in a Los Angeles courtroom by lawyers out to prove social media is dangerously addictive by design to young, vulnerable minds.

YouTube and Meta -- the parent company of Instagram and Facebook -- are defendants in a blockbuster trial that could set a legal precedent regarding whether social media giants deliberately designed their platforms to be addictive to children.
