Most radio stations have entered the digital age where not only is all the music, commercials, and other sound elements stored digitally on hard drives, but sophisticated software is also used to either
automatically run the station when a human can't be there or to help in
assisting a live DJ or personality in running the station.
There are various types of software designed to do this and it usually displays directly in front of the audio console where it it clearly seen by the person on-air.
This screen is displaying each element that has played and will play over the next 20 minutes or so. It is a digital version of the station's log.
