Mark Zuckerberg said very little on his first day of testimony—but the fact he’s here at all is a major moment

Other social networks chose to settle pre-trial, so bringing Zuckerberg to court suggests a shift in power. The social media trial brought by a 20-year-old Californian plaintiff known as Kaley or KGM, putting Meta and YouTube in front of a jury, has captured the world’s attention. The bellwether trial is a test case for the liability of social media platforms and how much they could be on the hook financially if found to have caused harm to their users. KGM, for her part, alleges that she faced anxiety, depression, and body image issues after using Instagram.
