On This Day in Business: February 4, 2004
On February 4, 2004, a Harvard student website called TheFacebook went live. Mark Zuckerberg built the service with help from fellow students Eduardo Saverin, Dustin Moskovitz, Andrew McCollum and Chris Hughes. The initial proposition was narrow: verified Harvard students could create profiles, list personal information and connect with people they knew on campus. That restricted setting gave the young network both relevance and trust. Instead of asking the entire internet to join an empty service, the founders launched inside a dense community whose members shared an institution, email system and strong curiosity about one another.
Adoption came quickly. Thousands of Harvard students registered during the first weeks, and the team extended the network to other Ivy League schools, then colleges across the United States and Canada. Each campus created a contained market with existing social connections, allowing growth to proceed one network at a time. The product benefited from a feedback loop: every new profile made the directory more useful, while real-name identity encouraged additional participation. Early financing and a move to Palo Alto during the summer of 2004 shifted the effort from a student project into a venture-backed company.
The company gradually removed institutional boundaries. High-school networks, workplaces and finally anyone meeting the age requirement could join. New features such as the News Feed changed Facebook from a directory that users visited into a stream that continuously organized updates. Advertising turned attention and identity data into the core commercial engine, while outside developers, publishers and businesses built around the platform. The model produced extraordinary reach, but it also generated difficult questions about privacy, competition, political influence, content moderation and the power of algorithms to shape what billions of people see.
February 4 is significant because the launch demonstrates how disciplined initial scope can help create a global platform. The founders did not begin with every feature or every audience. They solved a recognizable problem for one connected group, used scarcity to increase interest and expanded only after activity made the next network valuable. That sequence became a classic growth strategy for digital marketplaces and social products. The later company's impact cannot be separated from controversies that accompanied its scale, yet the business mechanics of the first release remain clear: verified identity, local density and network effects turned a simple campus directory into an infrastructure layer for communication, advertising and media distribution. The campus-by-campus rollout also gave the company a sequence of manageable experiments. Each school revealed how people used profiles, invitations and connections before the service entered a broader population, allowing product learning and market expansion to reinforce one another.
The first service targeted Harvard students, using institutional email addresses and a familiar campus community to create relevance and a measure of trust.
Profiles and friend connections made each new participant increase the directory's usefulness, producing a strong local network effect.
TheFacebook went live on February 4, 2004, and attracted thousands of Harvard registrations during its first weeks.
The founders expanded school by school before moving to Palo Alto and raising financing, converting a dorm-room project into a formal company.
Opening the service more broadly and adding the News Feed transformed a campus directory into a continuously used global media platform.
Advertising funded enormous growth while privacy, content governance and algorithmic influence became central business and public-policy challenges.
