Clearchannel is doing this nationwide. They are turning one of their stations into a Spanish-language station in 50 markets, IIRC.
Clearchannel's Spanish radio station here(upstate SC), LaBrava 1440, was just sold to an independant. It's still Spanish, but with a new name (Mix 1440). Something they do that English-speaking stations don't (that I know of), is cover soccer.
