Refers either to a comfortable on-air transition between songs or a positive career move. The former often can lead to the latter. The order in which records on the playlist are played. Like the gizmo John Madden uses on Sunday to diagram plays, Selector is a computer program that revolutionized radio programming by permitting the PD or MD to develop an on-air schedule without having to mix and match index cards or juggle records on a paper log.
Football has one, and so does radio.
The clock is a critical element of any station's tightly held programming strategy, serving as a firm template that indicates at what point in each hour of the day certain elements will be played. Clocks vary not only from station to station, but also from hour to hour. Think of all the football fans who don't get up and use the bathroom, fix nachos, or switch to the other game during the time-outs. The goal is to build this number by appealing to a core group of listeners who find the programming most appealing and therefore won't turn the dial. Casual listeners those who occasionally tune in add to AQH listening, but don't contribute as much overall as the core audience.
