I just remembered! My library was subscribing to the AJC back then, and once I started adding content to Wikipedia I was the one who added the history of 1160 and 1170.
Alternative- a REAL alternative station
LOL. The two Alternative stations had a combined 1.0 share. Definitely not a hole there.
There's more to that story than what you see with the 1 shares. Signal challenges/horrible management decisions (i.e. Woody Show). This is not a declaration that the format is prime for re-launch, but you can not discount based on your example either.
Five formats missing in Atlanta:
Someone else posted a similar list, and my comment to their list is the same: Almost all of those formats aim old. Unless a new owner buys some Atlanta stations, the current ones don't need any more old demo formats in their clusters.
The success of 97.1 The River in A25-54 and to a lesser degree A18-34 invalidates such a notion. One of the stations with the OLDEST median song age scores GREAT ratings.
Then playing older songs is not a missing format. It's already being done.
I think that the decades only formats work when you can jump between them... 60's and 70's or maybe 70's and 80's. But they are too narrow for terrestrial because one owner is not going to have an FM for the 60's, another for the 70's and so on.
The other issue is that the decades don't define music trends. 1955 to 1964 was one set, not 50's separate from 60's. And early 50's was Patty Page, not the early rock 'n roll era. And 1964 to 1972 or maybe 1973 was another era. There was a pause before we got 74's "Rock the Boat" which took us to 1980 and "Funkytown!"
So decades don't define music; that is an artificial set of bookends.
The problem is that a lot of songs from each era are ones that most listeners don't ever, ever, want to hear again.
Example: I really liked the Carpenters back when the songs were current and I was doing AC. I really don't want to hear those songs again, though. Same goes for Tom Jones or Neil Diamond or Mr. Humperwhatever...
interesting that there are 2 Three Dog Night songs released a few months apart. One can only be on 60s at 6 and the other can only be on 70s at 7 (among the SiriusXM decade channels).
