OT: Any top media markets there?
Depends on definitions a bit, but for all intents and purposes, yes.
The LA market tipped last year. The Miami-Ft. Lauderdale market tipped nearly a decade ago. The Houston market will be next.
As an aside, since you once lived here, you might find interesting to hear that it is becoming more commonplace for ads in Spanish to run on the major network channels during prime hours. A rather surreal experience.
