The questions from US lawmakers for tech bosses came thick and fast earlier - and there were plenty of punchy one-liners from senators.
It marked the first time many of the tech executives had testified before Congress. But not for Meta's Mark Zuckerberg - it was his eighth time and he faced the brunt of the questions as he was challenged over what Instagram and Facebook are doing to protect children online.
The most dramatic point was when Zuckerberg was essentially forced into apologising to family members in the room, many who say their children have been harmed as a result of social media use or content.
TikTok's boss Shou Zi Chew was also in the firing line, facing a grilling about whether his company shared US users' data with the Chinese government, which he denied.
Will this change anything? Let's see. As our correspondent Nomia Iqbal writes, Congress has only passed one children’s safety law in the last decade. But this hearing stood out compared to others - because of the families in the room.
