What's the impact of literature on journalism?

The impact of literature on journalism is most keenly felt by the development of New Journalism. New Journalism developed in the 1960s and was made famous first by Truman Capote who employed narration more often associated with fiction in his "non-fiction novel," as he called it, In Cold Blood. Tom Wolfe's book, The Electric Kool-Aid Acid Test, is another example of New Journalism, as are many of Joan Didion's essays on politics and popular culture in the 1960s.
While traditional journalism focuses solely on the facts of an event or a person of interest to maintain a distant, objective stance, New Journalism allows the writer's personal views and perceptions into the text. The writer of the piece is often a character, or participant, in the story's events. This is most evident in Gay Talese's work The Voyeur's Motel.
New Journalism focuses on character development and is more descriptive than a traditional article. Voices come alive through sustained dialogue. As opposed to merely reporting what someone says, a New Journalist will describe the context in which the quote was said and the mood of the speaker.
These days, this style of writing is particularly evident in magazines, such as The New Yorker and Harper's.
The main impact is that of a more elastic idea of the truth. Is the truth only the facts, or does it also include how those facts are expressed? Does personal narrative diminish the validity of a journalistic piece or enhance it?
