Meta Platforms, Inc. (formerly Facebook, Inc.) is the world's largest social media company, founded in 2004 by Mark Zuckerberg. The company rebranded to Meta in 2021 to reflect its expanded focus on building the metaverse and immersive experiences. As of Q1 2025, Meta's family of apps reaches nearly 4 billion monthly active users across Facebook (3.07 billion MAU), Instagram (2 billion MAU), WhatsApp (2 billion MAU), Messenger, and Threads (400 million MAU).

Facebook remains the flagship product and one of the most visited websites globally. The company operates on an advertising-based model, generating revenue primarily through targeted ads across its platforms. Meta has also expanded into hardware with Meta Quest VR headsets and is investing heavily in AI and mixed reality technologies. Threads, launched in July 2023, became the fastest app to reach 100 million users and now rivals X (formerly Twitter) in daily active users.

Meta operates its own authoritative nameservers (a.ns.facebook.com through d.ns.facebook.com) and runs one of the largest private networks in the world. The company is headquartered in Menlo Park, California, and is a significant contributor to open-source infrastructure projects including React, PyTorch, and various data center technologies.
