Apparently San Antonians prefer syndicated talkers and wall-to-wall Spurs coverage to local talk. Go figure. KTSA seems to be adding more syndicated fare with each passing year, but it'll be tough for them to compete with the 30 hours a week of the #1 and #2 syndicated national shows on OAI. They'll also be hard-pressed to pry that Spurs contract away.
Someone posted a while back that KTSA bills very well, despite its numbers.
