Meta Platforms runs the largest family of social apps in the world: Facebook, Instagram, WhatsApp and Messenger. Nearly all revenue comes from advertising, targeted using the engagement data those apps generate across billions of users. The company also invests heavily in its Reality Labs division, which develops virtual and augmented reality hardware such as the Quest headsets, and in artificial intelligence that powers content ranking and ad delivery. Meta was founded in 2004 and renamed from Facebook in 2021 to reflect its ambitions beyond social networking.
