From a Harvard social network to AI and wearables: how Facebook became Meta
Meta began as Facebook, a university social network created in 2004. Over the following two decades, the company expanded through messaging, photo sharing, virtual reality, advertising and acquisitions before changing its corporate name to Meta Platforms in 2021.
Mark Zuckerberg remains the defining founder and, as of 18 September 2026, continues to serve as founder and chief executive.
Facebook itself remains one of Meta’s largest platforms, but the company now also owns Instagram, WhatsApp and Messenger, operates the Quest mixed-reality platform and is investing heavily in AI infrastructure, models and wearable computing.
This history explains how a website built around student profiles became a company attempting to shape several generations of online communication.
Facebook began at Harvard in 2004
Facebook launched in February 2004 as TheFacebook, initially serving Harvard students.
The service expanded to other universities and then beyond academic networks.
Its basic premise was simple: users created profiles, connected with people they knew and shared information through an identity-based social network.
That model differed from anonymous forums and many earlier online communities because Facebook tied participation closely to real-world identity and relationships.
The News Feed changed Facebook from profiles into a continuous network
Early Facebook use centred heavily on visiting individual profiles.
The introduction of News Feed transformed the experience by bringing updates from many connections into one continuously refreshed stream.
This made Facebook more habitual and gave the company a central place to rank and recommend content.
Over time, algorithmic ranking became one of the most consequential — and controversial — parts of the platform.
Advertising turned social connections into a large business
Facebook built an advertising model around its knowledge of users, interests and interactions.
Businesses could target audiences more precisely than with many traditional media channels, while Facebook could keep the consumer service free.
Advertising became the economic foundation that funded the company’s expansion into new products and acquisitions.
The IPO made Facebook a public company
Facebook completed its initial public offering in 2012.
The listing gave investors direct access to a social platform that had already grown to enormous global scale.
That same year, Facebook made one of its most important acquisitions.
Instagram gave Facebook a mobile-first visual platform
Facebook acquired Instagram in 2012.
Instagram had built a fast-growing photo-sharing network centred on smartphones at a time when Facebook’s own future depended increasingly on mobile usage.
Instagram later expanded into video, Stories, Reels, messaging and creator tools.
The acquisition became one of the clearest examples of Facebook buying a platform that could have developed into a major independent competitor.
WhatsApp added global messaging at enormous scale
Facebook acquired WhatsApp in 2014.
WhatsApp brought a very different product model: private mobile messaging based on phone numbers rather than a public social feed.
The service became especially important outside the United States and developed into a communications platform used by individuals, groups and businesses.
Its end-to-end encryption also created a very different privacy architecture from Facebook’s public and advertising-driven products.
Oculus signalled a bet beyond phones
Facebook also acquired virtual-reality company Oculus in 2014.
The deal showed that Zuckerberg was already thinking about computing platforms beyond conventional social networking.
Oculus technology later evolved into the Meta Quest product family, giving the company a hardware platform it controls more directly than smartphones built around Apple or Google operating systems.
Facebook became Meta in 2021
On 28 October 2021, Zuckerberg announced that Facebook Inc. would become Meta.
The social network kept the Facebook name, but the parent company changed to reflect a broader strategy.
Meta said it wanted to build the “metaverse”, a concept involving persistent digital experiences spanning virtual and augmented reality.
The company also changed how it reported results by separating its Family of Apps and Reality Labs operations.
The rebrand did not make Facebook less important
Meta’s corporate name changed, but Facebook, Instagram, WhatsApp and Messenger remained central to the business.
The Family of Apps continued to generate the advertising revenue that funded long-term investments in Reality Labs and other technologies.
Meta therefore became a two-speed company: enormous established social and messaging platforms funding experimental hardware and computing bets.
Reality Labs made the long-term hardware strategy visible
Reality Labs develops virtual-reality, augmented-reality and wearable products.
Quest headsets grew from the Oculus acquisition, while Meta also developed smart glasses and other wearable interfaces.
The financial cost of these projects has been substantial, but Meta has treated them as strategic investments in computing platforms where it wants more control over the hardware and software stack.
AI moved to the centre of Meta’s strategy
By the mid-2020s, artificial intelligence had become central to almost every Meta product.
Machine learning already powered feed ranking, recommendations and advertising, but generative AI expanded the role further.
Meta developed the Llama family of AI models and integrated Meta AI into products such as WhatsApp, Instagram, Facebook and smart glasses.
The company also committed enormous capital to data centres, energy and compute infrastructure for training increasingly capable models.
Meta is trying to combine AI with personal devices
Meta’s 2026 strategy links AI with hardware more closely than before.
Smart glasses offer a way to place an AI assistant into a device worn throughout the day rather than limiting interaction to a phone screen.
Quest continues the company’s work in immersive computing, while Meta’s broader research includes augmented-reality displays and new interaction methods.
The long-term question is whether these devices can become mainstream computing platforms or remain complementary products beside smartphones.
Leadership remains unusually founder-controlled
Mark Zuckerberg has remained chief executive since Facebook’s earliest years and retains substantial voting control through Meta’s share structure.
That gives him more strategic continuity than executives at many similarly large public technology companies.
In 2026, Meta appointed Dina Powell McCormick as president and vice chairman, reflecting the increasing complexity of a company investing in massive physical infrastructure alongside software and social platforms.
Zuckerberg nevertheless remains the central decision-maker and public face of the company.
Meta’s history also includes difficult questions about platform power
Meta’s scale has repeatedly brought scrutiny around privacy, content moderation, competition, political advertising, youth safety and the social effects of recommendation systems.
Those issues are part of the company’s history because its products influence how billions of people communicate and discover information.
Meta has responded with changing policies, privacy controls, safety systems and regulatory engagement, while debates around platform responsibility continue.
How Facebook became Meta
Facebook’s transformation into Meta did not happen because the original social network disappeared.
Instead, the company accumulated platforms and technologies around it. Instagram expanded visual social media. WhatsApp and Messenger built large messaging ecosystems. Oculus created a route into virtual reality, while AI now influences ranking, advertising, assistance and hardware.
The 2021 rebrand made that broader ambition explicit.
As of 18 September 2026, Meta is still funded primarily by social and advertising businesses, but its strategic investments increasingly centre on AI infrastructure, models, wearables and new computing interfaces.
