In News War, FRONTLINE examines the political, cultural, legal, and economic forces challenging the news media today and how the press has reacted in turn. Through interviews with key figures in print, broadcast and electronic media over the past four decades -- and with unequaled, behind-the-scenes access to some of today's most important news organizations, FRONTLINE traces the recent history of American journalism, from the Nixon administration's attacks on the media to the post-Watergate popularity of the press, to the new challenges presented by the war on terror and other global forces now changing -- and challenging -- the role of the press in our society. The third hour of News War puts viewers on the front lines of an epic battle over the future of news. America's major network news divisions and daily newspapers are under siege, facing mounting pressure for profits from corporate owners, and growing challenges from cable television and the Internet, which are remaking the economics of the business and transforming the very definition of news. FRONTLINE talks to network executives, journalists, Wall Street analysts, bloggers, and key players at Google and Yahoo! who are all battling for survival and market dominance in a rapidly changing world of news. FRONTLINE also goes inside the embattled newsroom of The Los Angeles Times, one of the last remaining papers in the country still covering major national stories. Under severe pressure from Wall Street to cut costs and to compete for "eyeballs" in a new media world, editors at the paper are urgently trying to figure out what this means for their future news coverage and their public service mission.
