As mentioned before, the coverage area population is not likely to be passionate... or even mildly interested in collegiate sports of any kind. Except for a slice of the coastal communities, the area is Hispanic, Black, Asian and a bunch of other first generation immigrants like Persians. None of those groups is a big follower of local college sports, particularly football which is not "native" to any of the immigrant groups.
As I said here yesterday, "Remember, 80% of LA's population is Black, Hispanic, Asian and first generation immigrants from places like Iran and Lebanon and Egypt. Those are not, as groups, people interested in college sports. In particular, they come from place where American football is not an attraction."
The first thing to look at with KABC is the huge portion of the metro area it does not cover.
