As David has told us, the Hispanic population is mostly younger than the U.S. population as a whole. Meanwhile, the talk format skews older. And then, what do you talk about? U.S. politics? But many listeners aren't citizens yet. Mexican politics? Puerto Rican politics? Dominican politics? Who'd want to listen to talk about someone else's country?
In theory, you do local talk about local living. Much about dealing with life in the new(er) country. No politics except very local issues that affect local residents. Medical care, benefits, sending kids to school, keeping them out of gangs. Sports and, of course, soccer for those not from the Dominican.
How to deal with a traffic ticket. Immigration law. Relationships and family law. Criminal law. Dealing with a landlord. In other words, daily living and its challenges in a new country with new laws and rules.
And even among English-language talk shows, nobody seems to want to listen to general, non-political talk, except maybe for Dave Ramsey talking about getting out of debt.
That's not the case with first generation immigrants. No interest at all in local politics. Lot of interest in things about living in a new place. And the only ones involved in politics "from back home" are political refugees such as Venezuelans and Nicaraguans... groups that hope the socialist government will fall and allow them to go back home.
Ramsey actually employed a Spanish-speaking host to do a podcast based on his money philosophy. But I haven't heard about it for some time so maybe that failed too?
Anyone who has enough money to need financial advice speaks English well enough to seek out advice-givers in English. Every financial show in Spanish ever tried has failed.
Unless JVC simply subscribes to several syndicated morning humor shows, records them and runs them all day, as a sort of Spanish-language Hot Talk format?
The problem with humor is that it depends on very specific national origin language and terms. Generally, unless written very specifically in "neutral" Spanish, morning shows appeal mostly to one nationality or region.
The word for "young child" in Ecuador means "bus" in Puerto Rico. In Ecuador a "bug" is the vulgar term for "penis" in Puerto Rico. Like that example, there are thousands.
A working class person from Monterrey, Mexico, can not understand the "street talk" of a whole subset of people from Mexico City. Several recent movies about "the street" in Mexico City have had Spanish subtitles for the rest of Mexico to understand.
Three attempts at national talk networks in Spanish have failed miserably.
