Meta is facing a landmark trial in the United States, with prosecutors aiming to prove the company deliberately made Facebook and Instagram addictive for children. This legal battle is being compared to the social media giant's "big tobacco moment."

• The states are seeking financial penalties as high as $1.4 trillion and significant changes to Meta's apps.
• Key players include Meta, represented by its founder and chief Mark Zuckerberg, and a coalition of states including California, Colorado, Kentucky, and New Jersey.
• Jury selection began on Monday in Oakland, with opening statements expected on August 18.
