Commercial inventory is the biggest factor between the 2 Christmas Music stations. ETM caps it, while TS does not. I can tell you from buying both stations with my agency, the price between the two stations are significant. Over the years, at 102.5, there was not a huge demand from advertisers for Christmas music. Listeners seem to like it, but advertisers usually did not even know they changes format, which is what they did. It always seemed unfair to me that the stations just change their entire format overnight, but do not alert clients to that change. Like clients don't matter.
The rates in Buffalo at a station like STAR do not change much, as their is not that much demand. Some clients actually pull their advertisers when they realize the format has been changed.
I realize that the demo really did not change, but at this early point in the game, their are many listeners and advertisers who do not like the format change. They will go to other stations for a while. Remember as well, Sirius has many channels to choose from for Christmas, with no commercials. The great thing about Sirius is it's all about programming, not sales. I know a PD at Sirius and that is what he loves most. They focus entirely on the listener.
Last year, 102.5's Christmas ratings were good, but more disappointing than years before. Sales stagnant.
