The HuntleyBrinkley Report proved that a strong chemistry is what the viewers liked per a survey yet they only spoke to each other when one hand off a story to the other.
Huntley and Brinkley conveyed a strong chemistry, and a survey for NBC later found that viewers liked that the anchors talked to each other. In fact, aside from their sign-off, Huntley and Brinkley's only communication came when one anchor finished a story and handed off to the other by saying the other's name, a signal to an AT&T technician to switch the long-distance transmission lines from New York to Washington or vice versa.
