Meta has agreed to pay $17 billion and add stronger child-safety measures to its Facebook and Instagram platforms to end a landmark trial over teen social media addiction and settle claims filed by 47 states, state attorneys general announced Wednesday.

The DOJ said Friday that TikTok will pay $300 million immediately and another $100 million after an order vacates an earlier consent decree against its predecessor company, Musical.ly.
