Mark Zuckerberg built Facebook in a Harvard dorm room and, within seven years, turned it into a company with roughly 800 million users and a valuation approaching $100 billion. Journalist Emily Maitlis reports this account of that rise, securing a rare sit-down interview with Zuckerberg himself and tracing how a college project for ranking classmates became the dominant platform for how people communicate. The film checks the Hollywood version of events against the record, weighing the dorm-room rivalry and lawsuits dramatized in The Social Network against what actually happened. It also looks ahead rather than only back, examining Facebook's plans to turn the personal data it has gathered on its users into a new advertising model, one built on knowing exactly who is watching. Maitlis moves between company insiders and outside observers to show how a single idea about openness and connection reshaped not just social life online but the businesses now built around it.
