From Nicholas Lemann’s “The Murrow Doctrine” (The New Yorker: 23 & 30 January 2006: 38-43):
There is a memorable entry in William Shirer’s Berlin Diary in which he describes – as, in effect, something that happened at work one day – the birth of broadcast journalism. It was Sunday, March 13, 1938, the day after Nazi troops entered Austria. Shirer, in London, got a call from CBS headquarters, in New York, asking him to put together a broadcast in which radio correspondents in the major capitals of Europe, led by Shirer’s boss, Edward R. Murrow, who was on the scene in Vienna, would offer a series of live reports on Hitler’s move and the reaction to it.
