The fact that a format is successful in other markets does mean that translates to success in market number uno. It is only a success if it bills well. Otherwise, it is a failure.
I did read the TIO's first before I came to this.
I can only speak for dance music here but I do realize that we are in the most CONSERVATIVE radio market in the nation. I also see more spoken word formats happening on the FM dial before ANY music format
since radio (meaning "corporate") basically destroyed the notion, at least in NYC anyway, that those under the age of 30 care about FM since they have gone to digital media players, smartphones and social media. If there is a "failure" that would happen here, it's corporates thinking; basically cutting off their nose to spite their face.
Having said that, I also believe that if you give a VERY COMPELLING reason to get those listeners back somehow, a station can be successful and we are talking billings. Radio has become "McDonalds" in that sense and that has turned the young crowd off. Even though 92.3 Now, Z-100 and 'KTU have different approaches to their formats, there is still that "similarity" of sorts. I'm just saying perhaps add a LITTLE "spice" to things and you could have something!
New York City is a rhythmic market. Sure, you play whats known commercially but then you add in those elements that dance fans would like (I would go a bit MORE deeper than Pulse 87 would since EDM has taken off big and stay away from dance material that would date back to the days of Hot 103/97). I strongly believe such a station would bill well because you have the fanbase here that would tune in, thus bringing in advertisers that could reach to them. And if it's that compelling to bring back the younger crowd to the FM just to hear this, then you have something BIGGER going on and that could translate to other markets that are "dance friendly" such as Miami, Los Angeles, Chicago, Minneapolis. You get the point
I can't talk for the other formats. That would be up to those people that believe in them the same way I believe in dance
