[Air-L] Defining 'digital age'

Dear fellow AOIR members, I am writing about education in the digital age but I'm having a hard time pinning down a definition of the extremely broad term 'digital age'. Does anyone have any leads? Very broadly, I am most interested in the challenges posed by globally circulating discourses when we think that these discourses are 'nourished' only by certain voices and that meaning is constructed contextually.
