We'll come back to the question of whether and how we in the press should address the communication challenge of ISIS—this information insurgency, but first perhaps we need to look at the evolution of what we in the United States call "the mainstream media."

In this case: radio, which brought a level of accessibility to the illiterate —still a very large part of the American and European population in the 1930s—and a kind of immediacy that newspapers found it hard to match.
