If you travel around the country, you're likely to find quite a few small radio stations like this. I call them hobby stations, but that's probably not accurate. They are stations that play whatever the owner wants. You might call it Jack or Ben, but it's more likely "Kristin," who's now the owner. Not as catchy. They are really playing whatever they want. And yes the audience is a lot older than the normal target. But these are stations that aren't looking to appeal to advertising agencies, but rather get by with all local money. The reason stations like WOGL try to keep the demo under 55 is to get the big ad agency money. But if you're in such a small market that the agencies don't know you exist, you have to come up with other ways to pay the utility bill. That's what this station is doing. I looked at their coverage map, and couldn't come up with a familiar town. With a screaming 930 watts, they're not much of a threat to the bigger stations. But they have a repeater, so that helps.
Speaking of hobby stations, there are such streaming stations such as Tunein where there are several genres of "classic hits" stations to choose from. One example are those six stations that are dedicated to disco and classic dance music from the '70s and '80s. Almost every day I listened to one of the stations when I had nothing to do and some of the songs that played on one of their streaming channels in which many listeners like myself are not familiar with never gets played on classic hits stations such as WOGL or, locally, on the station that spawns several FM translators where I live in the Scranton area. Furthermore, the disco songs gets played in full length(roughly around seven to eight minutes) while on traditional radio the amount of airplay is limited to around four minutes in length. It would seem that Internet radio has no limits when it comes to what gets played. Heck, if a station like Jammin' Gold still exists, I would be listening to it for hours and hours on end because there would be more disco and other classic dance tunes than what WOGL currently offers!
As for Steve Green mentioning of the station calling itself "Hanna FM", I listened to them when I was in the Williamsport area and the one song that I heard was an '80s R&B song called "Nite and Day" by Al B. Sure. Other stations don't usually play it and it's probably only heard on mostly Urban stations.
