Person to Person, the celebrity interview show of the 1950s that saw Edward R. Murrow in a studio talking to guests in their homes, returned on Wednesday and promptly flopped. With most viewers unaware of the original term ("person to person" was an expensive long-distance calling rate in which an operator requested a specific person a caller demanded and there was no charge for The Call if the person was unavailable) and celebrities now being spotlighted every night of the week, the series debut drew only six million viewers, to put CBS in third place in the 8 00 p.m. period.
