KLTV 7.2 changed from This TV to Bounce on Jan 1, 2012. I was under the impression that the change on 19.3 from Azteca to This TV occured on June 1, 2012, but it may have occurred anytime after Jan. 1. I never watched 19.3 so had not noticed the change until Sunday. The Wikipedia article for KYTX still says Azteca on 19.3, and Tripinva's Rabbitears.info shows ThisTV on 19.3.
I fixed the Wikipedia page to show This TV for 19.3.
