Meta runs the social apps Facebook, Instagram, and WhatsApp and sells ads to the billions of people who use them.
Meta is, at its core, an advertising machine wrapped in free apps. Facebook, Instagram, WhatsApp, and Messenger cost nothing for ordinary people to use, and that is the whole point: the more people who scroll, post, and message, the more attention Meta can sell to advertisers. Nearly all of the company's money comes from companies paying to place ads in front of those users, targeted with unsettling precision based on what people share, click, and watch.
The business works because of a simple loop. Users bring their friends, families, and interests, which creates attention. Advertisers pay to reach that attention, and Meta uses the money to improve its apps, buy back stock, and build new things. It competes fiercely with TikTok, YouTube, and other apps for people's screen time, and its scale is its shield: with billions of users across its apps, even a modest slice of global ad spending turns into enormous revenue. Meta also owns a small but growing slice of the hardware world through its Ray-Ban smart glasses and Quest virtual-reality headsets, though those are still minor compared with advertising. Meta is run by Mark Zuckerberg, who controls a large share of voting power, meaning outside shareholders own a slice of the company but have little say in how it is run. That structure let him pour billions into the "metaverse" project starting in 2021 — a bet that immersive virtual worlds would become the next computing platform. The bet has been expensive and slow to pay off, and the division that houses it, Reality Labs, has lost tens of billions of dollars. More recently Meta has pivoted hard toward artificial intelligence, spending heavily on chips and data centers and adding AI features and chatbots across its apps.
In his Harvard dorm, Mark Zuckerberg built Facemash, a site that compared student photos side by side. It went viral almost at once, and the university shut it down within days. The trouble pushed him to drop out as a sophomore. That little scandal site was the direct ancestor of the social network that became Meta.
Zuckerberg launched TheFacebook with Eduardo Saverin, Dustin Moskovitz, and Chris Hughes. It let Harvard students build digital profiles and connect with each other. From there it spread quickly to other campuses and beyond, planting the seed of a global network.
For its first years, Facebook was a walled garden for college students only. Then it opened membership to the general public. That move set up the huge audience that would make its advertising business so valuable.
Facebook acquired Instagram for roughly a billion dollars in cash and stock. It added a major mobile photo-and-video platform to the company's lineup.
Facebook went public at $38 a share in a record-breaking tech IPO valued around $104 billion. Then the stock fell more than 30% in its first year, as people doubted the company could make money on phones. It later recovered and became one of the most valuable tech companies in the world.
Facebook bought WhatsApp for about $19 billion and the virtual reality company Oculus for $2 billion. WhatsApp widened its messaging reach, while Oculus became the foundation of its later metaverse push.
Cambridge Analytica improperly harvested personal data from up to 87 million Facebook users. The FTC later fined the company a record $5 billion for privacy violations. The scandal badly damaged its reputation and turned up the heat on Big Tech.
Facebook rebranded its parent company as Meta Platforms, with Facebook becoming a subsidiary. Zuckerberg framed the change around the metaverse, an immersive next chapter of the internet. Critics called it a distraction from whistleblower revelations about harm on the platform.
Meta launched Threads, a microblogging app built to rival Elon Musk's X. The launch showed Meta using its Instagram base to compete in new social formats.
Meta launched Muse, a personal AI agent that carries out real-world, multi-step tasks in the background. Zuckerberg positioned personal superintelligence as the company's next major platform shift. The AI push is expensive, and Meta increasingly shifted its focus from the metaverse toward AI.
The company's most important vulnerability is regulation. It faces antitrust scrutiny in the United States and Europe, and European rules like the Digital Markets Act constrain how it operates. Apple's privacy changes in 2021, which let iPhone users block tracking, dented Meta's ad targeting and cost it billions in revenue — a reminder that Meta depends on other companies' platforms to reach some of its users. Still, Meta generates huge free cash flow, which it has used aggressively to buy back its own shares in large amounts, shrinking the share count and lifting earnings per share. For all the metaverse drama, the ad business remains the engine, and it keeps humming.
