When we named Mark Zuckerberg TIME’s 2010 Person of the Year Lev Grossman wrote, “Facebook has merged with the social fabric of American life, and not just American but human life: nearly half of all Americans have a Facebook account, but 70% of Facebook users live outside the U.S. It’s a permanent fact of our global social reality. We have entered the Facebook age, and Mark Zuckerberg is the man who brought us here.”
Lev revisits that cover story and notes what’s changed since then.
