LOS ANGELES (AP) — Univision Radio Network's nationally syndicated Spanish-language program "Piolin por la Manana" has been canceled.

Univision spokeswoman Monica Talan confirmed the cancellation in an email to The Associated Press on Tuesday.

Univision did not release the reason for dropping the morning talk show hosted by Eddie "Piolin" Sotelo.

The Los Angeles Times reports (http://lat.ms/15cC3rC), however, that it had been eclipsed in the competitive market.

The Times says, for example, that Ricardo "El Mandril" Sanchez's program of regional Mexican music took over the No. 1 spot in the Los Angeles-Orange county market's Arbitron ratings last month.

In addition to his program's madhouse style, Piolin used his popularity to urge his audience to turn out for immigration reform events and to push Hispanics to wield their clout in elections.
