The Conversation:

For a few years now, alarms have been sounded in various quarters about Facebook’s teen problem. In 2013, one author explored why teens are tiring of Facebook, and according to Time, more than 11 million young people have fled Facebook since 2011. But many of these articles theorized that teens were moving instead to Instagram (a Facebook-owned property) and other social media platforms. In other words, teen flight was a Facebook problem, not a social media problem.

Today, however, the newest data increasingly support the idea that young people are actually transitioning out of using what we might term broadcast social media – like Facebook and Twitter – and switching instead to using narrowcast tools – like Messenger or Snapchat. Instead of posting generic and sanitized updates for all to see, they are sharing their transient goofy selfies and blow-by-blow descriptions of class with only their closest friends.
