A pair of popular morning drive DJs during the '80s was celebrating 10 years in radio as a team. One of them asked the other, "You've named all the newscasters we've had since we've been here. Now, can you name all the program directors we've had?" The other DJ's response: "Got an hour?"
Given the precarious ratings book-to-ratings book status by which program directors are retained or let go, the DJ's response, though not meant literally, contained an uncomfortable ring of truth.
