I remember hearing revenue was down at KXTD 1530. I think I saw that piece on the web, but I can't remember which TV station did it. I was in Tulsa visiting family just 10 days ago, and there hadn't been any format changes on Spanish language radio from the previous time I was there in June.
It looks like a lot of other businesses may be affected before radio. I read a newspaper article, possibly in the Oklahoma Observer, stating business leaders all over the state were urging a delay, if not an outright repeal, of some of the provisions of the bill. I believe most of them were saying the new requirements on businesses were too expensive and that some provisions delegated police and immigration duties to them.
