The landmark trial against Meta, the parent company of Facebook and Instagram, has commenced in California. A coalition of states is accusing the tech giant of deliberately making its platforms addictive for children.

• States are seeking approximately $200 billion in damages and demanding changes to Meta's apps.
• Key players include Meta, led by founder Mark Zuckerberg, and lawyers representing California, Colorado, Kentucky, and New Jersey.
• A significant early development saw the judge dismiss Meta's attempt to block testimony from former employee and expert witness Arturo Bejar.
