Is private life disappearing before our eyes?

Questions surrounding the line between private and public lives were among the many raised earlier this month when a video of a tech CEO and his company's HR manager embracing at a Coldplay concert went viral. In her book Strangers and Intimates, cultural historian Tiffany Jenkins explores the relatively short history of the notion of a private life. She joins David Common to explain how the phenomenon came to be, the value she thinks it holds, and why she fears it may be disappearing as technology continues to erase the line between private and public.
