 Bergman's reporting for ABC was noted for its direct style.In contrast to the more avuncular style of CBS anchor Walter Cronkite, Bergman's reporting took a very serious tone, and was very direct (to the point of seeming pessimistic at times) about the possible consequences of any mishaps or accidents that took place during a spaceflight, such as the Apollo 13 accident.In order to more fully understand the astronauts and their missions, Bergman often took part in the same training and simulations that the astronauts did.
