Richard Diamond's Car-Phone -  The detective drama RICHARD DIAMOND, PRIVATE DETECTIVE/CBS/NBC/1957-60 was one of the first shows to feature a telephone in a car.

Richard Diamond (David Janssen) took his messages from a Hollywood answering service girl called "Sam," a faceless receptionist with a sultry voice and great pair of legs.

While Richard cruised the streets of Los Angeles, Sam often called Mr. "D" (as she called him), just in time to supply him with information that saved him from the bad guys.

Sam was played by a young Mary Tyler Moore (February-May 1959) and replaced by Roxanne Brooks (1959-60).
