Ned is the first station manager of KACL seen. Bob "Bulldog" Briscoe had a physical fight with him, when Briscoe thought he was going to be fired. Miller himself was fired, after dispensing with the services of Frasier, because the station wanted to cut his high salary. He was replaced as station manager by Tom Duran.
Miller is married, but his wife supposedly hits on other men.
While never seen again in the series, he is referred to later in Episode 12 of Season 1, where Frasier thanks him for retelling of how he was mugged on the way back from a soup kitchen (implying that he had become destitute and/or homeless since being fired from the station).
