Facebook launched on February 4, 2004, from a Harvard University dorm room

Mark Zuckerberg created Facebook as a college networking site called "TheFacebook" when he was a 19-year-old Harvard student. The platform started as a way for students at Harvard to connect with each other online, similar to printed face books that some colleges distributed to help students get to know their classmates.

The site was initially only open to Harvard students. Within 24 hours of launch, more than 1,000 Harvard students had signed up. Within a month, more than half of Harvard's undergraduate population had a profile on the platform.

Key Takeaways

  • Facebook launched on February 4, 2004, as "TheFacebook" from a Harvard dorm room run by Mark Zuckerberg.
  • The platform expanded from Harvard to other colleges and universities before opening to anyone 13 and older with a valid email address in September 2006.
  • Facebook reached one million users by December 2004, less than a year after launch.
  • The site changed its name from "TheFacebook" to "Facebook" in 2005 after Zuckerberg purchased the domain name.

Expansion to other colleges and universities

After proving the concept worked at Harvard, Zuckerberg and his co-founders expanded Facebook to other universities. By the end of 2004, Facebook was available at 34 colleges and universities across the United States. The platform grew by opening to one new school at a time, which helped maintain the quality and safety of the network as it expanded.

Each new school that got access to Facebook saw rapid adoption among its students. The strategy of limiting the platform to college students made it feel exclusive and gave students a reason to join — they could connect with people they actually knew or might meet on campus.

Opening to the general public in 2006

Facebook remained a college-only platform for its first two years. On September 26, 2006, the company opened registration to anyone 13 years old or older with a valid email address. This was a major turning point that transformed Facebook from a college networking site into a platform for the general public.

The decision to open to everyone meant Facebook could grow far beyond the college population. Within weeks of opening to the public, millions of non-college users joined. Parents, grandparents, and people of all ages began creating accounts to connect with friends and family.

Early growth and milestones

Facebook's growth in its early years was remarkably fast. The platform reached one million users by December 2004, just ten months after launch. By September 2005, Facebook had expanded to 200 colleges and universities and had over two million users.

In 2005, Zuckerberg purchased the domain name "facebook.com" and changed the site's name from "TheFacebook" to simply "Facebook." The company also moved its headquarters from Harvard to Palo Alto, California, to be closer to Silicon Valley's tech industry and venture capital funding.

Why Facebook succeeded where others failed

Several factors made Facebook different from earlier social networking sites. The platform required users to provide their real names and connect with people they actually knew, which created a more authentic network than anonymous or pseudonymous sites. This real-identity approach made the platform more trustworthy and useful for staying connected with friends and family.

Facebook also had a clean, simple design that was easy to use. The site focused on core features like profiles, friend connections, and a news feed that showed what friends were doing. This simplicity made it accessible to people who were not tech-savvy, which helped it reach a much broader audience than earlier social networks.

The role of venture capital and funding

Facebook's rapid expansion was fueled by venture capital investment. In 2004, the company raised $500,000 in seed funding from angel investors. In 2005, Facebook raised $12.7 million in Series A funding from venture capital firms, which gave the company the money it needed to hire staff and expand to new markets.

This funding allowed Facebook to grow much faster than it could have if Zuckerberg had tried to bootstrap the company on his own. The money paid for servers to handle millions of users, engineers to build new features, and business staff to manage partnerships with schools and other organizations.

Frequently Asked Questions

Was Facebook really the first social network?

No. Sites like Friendster (launched 2002) and MySpace (launched 2003) existed before Facebook. However, Facebook's focus on real identities and college networks made it more appealing to mainstream users than earlier platforms, which is why it eventually became the dominant social network.

Why did Facebook start at Harvard instead of somewhere else?

Mark Zuckerberg was a student at Harvard when he created the platform. He built it to solve a problem he saw at his own school — students wanted an easy way to connect with classmates online. Starting at Harvard gave him a built-in user base of people he knew.

How long did it take Facebook to reach one million users?

Facebook reached one million users in December 2004, about ten months after its February 2004 launch. This was considered extremely fast growth for a social network at that time, and it showed that the platform had found something people wanted.

What was the original name of Facebook?

"TheFacebook" was the original name when it launched in 2004. Zuckerberg changed it to "Facebook" in 2005 after purchasing the domain name. The new name was shorter and easier to remember, which helped with marketing and word-of-mouth growth.

When did Facebook become available outside the United States?

Facebook began expanding internationally in 2005 and 2006, opening to universities and then the general public in other countries. By 2008, Facebook was available in dozens of countries and had become a truly global platform, though the exact timeline varied by region.
