The fact that there is something other than all night infomercials tells you that the stations are trying to put on something reasonably interesting. I tune the AM band at night and hear interesting stuff most of the time. The FM stations play music all night, usually the same songs they play during the day with a few deep cuts thrown in here and there perhaps.Well, lots people here always disagree when I make my points in some of the forums. All I can say is if you expect and plan to fail you will. If you try to put something on air worth listening to it may work and be competitive. Instead so many advocate that the battle is already lost so why bother. Put on prerecorded news, infomercials, maybe the sound of a fog horn. Who cares - no one is listening so why bother trying to get anyone to listen. It's amazing to me how so many are in favor of just standing by and watching the ship go down without a fight.
I'm just a listener - I have no stake in the game. I love good radio and will listen when I find it - but if the radio industry won't provide that anymore it doesn't affect my my income and I'll find something else to do for entertainment. Those of you losing radio jobs because you resigned yourself to defeat can take my order at the McDonalds drive thru.
NPR overnights is the BBC on the local FMer and also on the AM NPR and JPR stations I hear from Oregon at night. Some Canadian stations have all night talk as well. The CBC plays various replays and sometimes the BBC overnights. One SFO station replays San Francisco Giants games before it goes network sports talk.
The problem is that the money isn't there for them to have local, top draw shows like maybe they did 30-40 years ago. But the stations make do.
