Book excerpt: Fred Friendly (1915-1998) was the single most important personality in news and public affairs programming during the first four decades of American television. Portrayed by George Clooney in the film Good Night and Good Luck, Friendly, together with Edward R. Murrow, invented the television documentary format and subsequently oversaw the birth of public television. Ralph Engelman's biography is the first comprehensive account of Friendly's life and work. Juggling the roles of producer, policy maker, and teacher, Friendly had an unprecedented impact on the development of CBS in its heyday, wielded extensive influence at the Ford Foundation under the presidency of McGeorge Bundy, and trained a generation of journalists at Columbia University during a tumultuous period of student revolt. Drawing on private papers and interviews with colleagues, family members, and friends, Friendlyvision is the definitive story of broadcast journalism's infamous "wild man," providing crucial perspective on the past and future of American journalism.
