The SXM model is not entirely fair to use in this instance. SiriusXM is based on subscribers. If enough listeners feel not having Escape on satellite is enough to stop subscribing, that directly translates to lost revenue. Even though running the radio station Escape costs SXM money, not running it equates to less paying customers.
KIXI, like most terrestrial stations, does not operate on a subscriber model. Hubbard knows that if they were to pull KIXI, a few folks would scream bloody murder, a facebook page with a hundred or so 'likes' to 'Save KIXI', and that would be it. Advertisers and Bulldog basketball goes to 1190 or stay with the new format. Hubbard knows nobody else will attempt to operate a major-market signal (AM or FM) with this format as they probably couldn't make it financially solvent. When the day comes when KIXI can't pay the bills with the format (or even afterwards, Hubbard likes AM music formats even if they're not really viable...see "820 The Gamut" in DC) they will unplug the automation, switch it to whatever, tell all the big band/standards fans to deal with it, and move on.
I can only think of two instances out of thousands of format flips (WNCN--WQIV--WNCN New York in 1974-75, and WXXM in Madison, WI with its Progressive talk format) where the listeners actually were able to change the course of a station's formatics. In both cases, it was not right away...the owners had to see a major dip in revenue (or less than projected) before it happened.
