The Early History of Facebook Explained

Mark Zuckerberg's Initial Vision and the Harvard Dorm Launch

Facebook began in a Harvard University dorm room in January 2004, created by Mark Zuckerberg, a 19-year-old computer science student. Zuckerberg didn't set out to build a global social network from the start. Instead, he created a simple website called "TheFacebook" as a project to connect Harvard students with one another. The platform allowed students to create profiles, upload photos, and see information about their classmates. At its core, it was essentially a digital version of the printed "facebooks" that colleges had distributed for years to help students get to know each other.

Zuckerberg launched TheFacebook on February 4, 2004, and the response was immediate and overwhelming. Within 24 hours, over 1,000 Harvard students had registered. Within one month, more than 50 percent of the Harvard undergraduate population had created profiles. This rapid adoption showed there was genuine demand for an online platform where young people could connect and share information about themselves. The success at Harvard caught the attention of other Ivy League universities, and Zuckerberg began expanding TheFacebook to Yale, Columbia, and Stanford in the following months.

What made TheFacebook different from other early social networks was its focus on real identity and real networks. Unlike sites such as Friendster or Myspace, which allowed anonymous profiles and emphasized random connections, TheFacebook required users to verify their real names and connected people within the same schools and institutions. This approach created a sense of authenticity and safety that appealed to college students. The platform became a way to maintain social hierarchies and relationships that already existed in the physical world.

Zuckerberg's early business model was not primarily focused on making money. Instead, he was driven by the goal of creating a useful tool for social connection. However, the rapid growth and widespread interest from investors and other companies quickly made it clear that TheFacebook had significant commercial potential. By the end of 2004, less than one year after launch, TheFacebook had expanded to 34 college campuses and had over 200,000 active users.

Practical takeaway: Understanding Facebook's origin as a college-specific network helps explain why the platform initially focused on age-verified users and real identities. These foundational principles shaped how the company approached user verification, privacy, and community building during its earliest years.

The Expansion Beyond College Campuses

During 2005 and 2006, Facebook (the company dropped "The" from its name in September 2005) expanded rapidly beyond its original college market. The company opened registration to high school students in September 2005, followed by expansion to corporate networks, such as companies and organizations. This expansion was crucial to Facebook's growth but also marked a shift in the platform's character. What had started as an exclusive network for college students began to become a mainstream social network.

In September 2006, Facebook made one of its most significant strategic decisions: it opened registration to anyone age 13 and older with a valid email address. This decision transformed Facebook from a niche college social network into a platform for the general public. Previously, if you were not in college or part of a high school or corporate network, you could not join. After September 2006, anyone could create a Facebook account, which dramatically increased the platform's potential user base. Within weeks, Facebook's user growth accelerated. By the end of 2006, Facebook had approximately 12 million active users, compared to just 5.5 million at the start of the year.

This expansion strategy was not without controversy. Many early Facebook users, particularly college students, felt that opening the platform to younger teens and non-students diluted the exclusivity and changed the platform's culture. Some users worried about privacy and safety concerns associated with younger users joining. However, the business logic was sound: opening Facebook to a broader audience meant exponential growth in total users and, consequently, increased advertising potential. The company began experimenting with targeted advertising and other revenue models during this period.

The expansion also required Facebook to develop new features and tools. As the user base became more diverse in age and background, Facebook introduced new ways to organize and manage friend lists, control privacy settings, and customize one's profile. The News Feed, introduced in 2006, became one of Facebook's most important features, automatically displaying updates from friends and pages in users' feeds. This feature fundamentally changed how users consumed information on Facebook and set the stage for the algorithmic feed system that would become central to Facebook's business model.

Practical takeaway: The opening of Facebook to all ages and the removal of network-based restrictions was a turning point that transformed it from a niche social network into a mass-market platform. This decision illustrates how social networks can shift their focus and user base as they pursue growth.

Funding, Investment, and Business Model Development

Facebook's early funding history reveals how the company grew from a college project into a significant commercial enterprise. In 2004, Zuckerberg initially rejected offers from other companies who wanted to purchase Facebook. Instead, he chose to raise venture capital funding to fuel the company's growth. The first major investment came from Peter Thiel, the co-founder of PayPal, who invested $500,000 in May 2004. This was one of the earliest venture capital investments in Facebook and gave the company legitimacy in the tech investment world.

In 2005, Facebook raised a Series A funding round of $12.7 million from Accel Partners. This funding allowed the company to hire more engineers, expand its server infrastructure, and open an office in Silicon Valley. The Series B funding round in 2006 brought in $27.5 million from Greylock Partners and others. By 2007, Facebook had raised over $60 million in funding, valuing the company at over $500 million. These investments were crucial not only for providing capital but also for validating Facebook's business model and attracting top talent to the company.

During these early years, Facebook experimented with various approaches to generating revenue. The initial approach focused on targeted advertising, similar to Google's model. Facebook developed tools that allowed advertisers to target users based on their profile information, interests, and behavior on the platform. This was revolutionary at the time because advertisers could reach specific audiences in ways that traditional media did not allow. However, advertising alone did not generate significant revenue in the early years. Facebook also explored other revenue models, including charging users for premium features and virtual gifts.

The turning point in Facebook's business model came in 2007 with the introduction of Facebook Ads and Beacon. Facebook Ads allowed companies to purchase targeted advertising on Facebook's platform, with prices determined by a bidding system. Beacon, while controversial due to privacy concerns, allowed companies to track user purchases and behavior off of Facebook and display that information to users' friends. These tools demonstrated the value of Facebook's user data and its ability to connect that data to commercial activity.

Practical takeaway: Facebook's revenue model evolved from a platform-first focus to recognizing the commercial value of user data and targeted advertising. Understanding how early social networks monetized their user bases provides insight into the business principles that shaped Facebook's growth strategy.

Competition, Key Competitors, and Platform Differentiation

When Facebook launched in 2004, it was not entering a completely empty market. Several social networks already existed and had millions of users. Understanding these competitors and how Facebook differentiated itself explains why Facebook was able to overtake other platforms and become dominant. Friendster, launched in 2002, was one of the earliest social networks and had millions of users, particularly in Asia. Myspace, launched in 2003, was another major competitor that actually had more users than Facebook for several years. In 2008, Myspace had approximately 116 million users compared to Facebook's 100 million users. By 2009, however, Facebook had overtaken Myspace in user numbers, a position from which it never relinquished the lead.

Facebook's key differentiators from its competitors included its focus on real identity and real networks, its cleaner user interface design, and its faster platform development. Unlike Myspace, which allowed extensive customization of user profiles and became cluttered with music players, graphics, and advertisements, Facebook maintained a simple, standardized design. This made Facebook faster to load and easier to navigate. Additionally, Facebook's emphasis on verified real identities and genuine connections between people aligned better with how young people actually wanted to interact online. Friendster, despite its early start, suffered from technical problems and eventually was overtaken by Facebook.
