Facebook Using first 2004 Billion People with Mark-Zuckerberg

On Sept. 14, the company reached 1 billion active users. In an exclusive interview with Bloomberg Businessweek’s Brad Stone and Ashlee Vance, Zuckerberg reflected on the milestone and what’s next for his company as it resurfaces from a wave of negativity.
