The social graph wasn’t always public. When Mark Zuckerberg, Eduardo Saverin, Dustin Moskovitz, and Chris Hughes launched the platform in 2004, it was strictly for Harvard students. They were all attending the university. That exclusivity ended quickly. By 2006, the gate opened to anyone over age 13. The shift changed everything.
User growth and the 2011 milestone
The network exploded. By the end of 2011, Facebook had 845 million users. That made it the largest social network in the world at the time. The scale was massive, but the business model remained simple. Access to the site is free of charge. You do not pay a subscription fee. So how does the company survive?
How Facebook earns revenue from free access
The answer is advertising. The company earns most of its money from ads. Users create profiles, upload photos, and signal their approval of content with the Like button. These actions generate data. That data sells ad space. The News Feed is central to this mechanism. It informs users of changes to their friends’ profiles and status. It keeps you on the site longer. More time on the site means more ad impressions.
The 2012 IPO and public markets
The following year, Facebook’s initial public offering (IPO) raised $16 billion. That was a landmark moment. The company went public. The valuation reflected its dominance. However, privacy remains an ongoing concern. The trade-off is clear: free access requires data collection. Users give up some privacy for free service.
The numbers tell the story. 845 million users by 2011. $16 billion raised in 2012. The model works, but it comes with costs. Who pays? You do. Not in dollars, but in data.
