I've never seen as many Spanish-only independent television stations as I have seen in the Los Angeles area. There appeared to be six of them. If my memory serves me correct, there was roughly the same number of independent Spanish stations as there were English stations. It appears they want to assimilate (sarcasm).
On the radio dials, there are a lot of Spanish stations, too. In southern California, there are a lot on the dial. I noticed similar numbers in Phoenix, Dallas-Fort Worth and Houston.
