In 2010, at the launch of Facebook’s then-new messaging service, Mark Zuckerberg predicted the decline of electronic mail, stating that “Email is too slow … email is too formal.” Time is proving Zuckerberg right. From December 2009 to December 2010, time spent using email by the 12- to 17-years-old age group dropped a tremendous 59%. In comparison, time spent using email by people 55 to 64-years-old has
increased 22%, and it has increased 28% among those 65 years and older.
