Yesterday I was driving to Jennifer’s house—my super-human sister who also resides in the Central Valley of California. I was surfing through radio stations and, after a bit, I noticed that far more than half were in Spanish.

Spanish radio stations have long dominated the air waves in the rural, agricultural areas of California. I called Jen and we tried to predict how much time we had left before Spanish radio conquered the major media markets.

I said five years—Jen said five days. The closest guess would win.

Then, this morning, reader E.B. sent me an email with this link: Radioandrecords.com

The listener demographics for Phoenix, Arizona are:

12+ Population: 2,856,900

Next Update: May 31, 2005

And, according to the Winter 2005 Arbitron ratings (just released), the top radio station for this major media market is—KHOT-FM/KHOV-FM from Univision…“regional Mexican” music.

I wonder which city is next.

I’ll get to ponder that with my sister over the payoff dinner I now have to buy Jen…lucky guess, sis.
