In the mid-1950s, Edward R. Murrow was the dean of broadcast journalism-a genre he had pioneered. Hired as director of news by CBS in 1935, Murrow broadcast the outbreak of war in Europe; from 1938 to 1945, his signature opening, "This . . . is London," brought the war into American living rooms. In the postwar's new medium, television, Murrow launched See It Now (1951-58), a news documentary program that he called "an entirely new weapon of journalism." Its high point was a March 1954 broadcast that helped topple Senator Joseph McCarthy. Murrow also hosted the popular Person to Person, in which he visited celebrities in their homes during prime time (1952-61). Murrow left CBS in 1961 and directed the United States Information Agency until his death in 1965.
