Maybe true, but a couple of other issues were at play...
1.) The margins for talkradio are pretty slim. If you have a $65 million dollar FM, the return can't be less than 1%. WRKO's "bar" is set much lower.
2.) It appears the PPM hit WTKK particularly hard. (Back then, there was a thought I've heard that "talky" morning shows and talk stations on FM did not fare well in the PPM world.)
3.) WTKK had many other options and music formats with much more upside than WRKO did. WRKO had to stay talk. WTKK could morph into any format that seemed available and workable.
Where I read explanation, if we hypothetically flipped WTKK's air staff and WRKO's air staff at the time, could have WTKK stayed with the format longer? Could it pull in the ratings and billing today that WRKO pulls in? I know ratings and billing are two different metrics.
Again, it's completely hypothetical. I agree that there are more options for formats on an FM station than on an AM station. WBTQ is showing to be a viable station for Beasley. From the relative time around it's flip from "Talk" to "Hot" until now, we've watched WKAF/WRZM flip formats three times, WODS/WBGB flip formats twice, and WBOS tweak/flip formats twice. On the flip side, WRKO couldn't have flipped to "Hot 680" and been successful. Options on AM at the time were either Sports (which was covered on FM and WRKO's then-owner had WEEI), Spanish language talk or music, Christian music, or leasing it out. I'm sure I'm missing some other known AM options. Even then, the "Oldies" format wasn't as prevalent on the AM band as it is now.
I agree that when WTKK flipped perhaps WRKO needed to stay talk. I don't see it as needing now. It draws ratings, thus the following is a nonsense discussion; so, I present it as hypothetical only. If WTKK stayed around, and ended up having stronger ratings and stronger billing than WRKO, I question whether WRKO would go with an Oldies format, as some AM stations are doing in the area. It would have the reach. Would some nostalgia come into play from the 54+ demo for a revival of "The Big 68?" Again, not that WRKO flipping would be even questioned in reality, given the ratings it is pulling in. I hypothesize that had WTKK had the air staff that was present on WRKO, we would likely still have "Talk 96.9," yet might not have the current format of WRKO.
