Gross, Terry. Fresh Air . NPR. 2 Oct. 1997. In a 35-minute radio interview, DeLillo discusses the headlines that inspired Underworld's prologue, describes videotapes as "our last perception of nature," and reads from Underworld , pp. 158-59. He then talks about: Diana's death, the deaths of Oswald and Kennedy and the mediums on which they were recorded (TV vs. film), news that has a "tabloid emptiness at its heart" replacing the Cold War narrative, the relationship between technology and paranoia, Underworld 's title, the "American language" of his novels, "rediscovering" the "argot" of the Bronx, being shaped more by the Cold War than by World War II, the Italian language, his "audio-visual connection to language" (not only the sound but "the physical appearance" of words on the page), the second person singular in Underworld , his penchant for "larger themes," the writer's need to resist "consumer culture," and the function of celebrities in contemporary life.
