Back in July, I was sitting in my office at school, working on a syllabus for a new sophomore- level class on language and society. I was exploring the U.S. Census Bureau website to get a sense of the most current information we have about language communities in the United States. I had the radio on, too, and while I was browsing census data about Nebraska, I heard an advertisement on one of the FM stations. The ad was primarily an English-language ad, but it also had a few Spanish words. It turned out to be a job advertisement for a radio station in the city that wanted to hire a Spanish/English bilingual speaker to be a sales director. I don't know if this is the first time an advertisement of this sort has aired in Omaha, but I suspect it is quite rare.
