Facebook, Inc.

Co-dominant force in global digital advertising alongside Google, commanding a significant share of worldwide digital ad spend through its family of apps

Facebook, Inc. was founded in 2004 by Mark Zuckerberg and co-founders at Harvard University, growing from a college social network into one of the most influential technology and advertising companies in history. On October 28, 2021, the parent company formally rebranded to Meta Platforms, Inc., reflecting a strategic pivot toward building the metaverse — though the Facebook social platform itself continues to operate as a core product under the Meta umbrella alongside Instagram, WhatsApp, and Messenger. The Facebook platform remains a cornerstone of the global digital advertising industry, offering advertisers unparalleled audience scale with over 3 billion monthly active users. Its advertising ecosystem — now managed under Meta's unified Ads Manager — provides sophisticated targeting capabilities powered by first-party social graph data, behavioral signals, and cross-platform identity resolution across Meta's family of apps. This makes it one of the most powerful performance and brand advertising environments available to marketers of all sizes. In the AdTech landscape, Meta Platforms (formerly Facebook, Inc.) competes directly with Google as a duopoly force in digital advertising, collectively commanding the majority of global digital ad spend. The platform's self-serve advertising tools, advanced audience segmentation, pixel-based retargeting, and AI-driven campaign optimization (via Meta Advantage+) serve everyone from small businesses to Fortune 500 brands. Despite ongoing regulatory scrutiny around data privacy and antitrust concerns, Meta's advertising business generated over $130 billion in annual revenue as of 2023, underscoring the enduring commercial power of the platform originally built as Facebook, Inc.
