U.S. Hispanics aren't the only culture in the U.S. that speaks another language and could be marketed to differently. Like U.S. Hispanics, Korean Americans aren't one solid demographic you can market to by translating your content into their language. However, this article does note that "About 70 percent of all Koreans surveyed in the 2000 U.S. Census said they were not born in the United States. Compared with other ethnic groups, Korean immigrants and Korean Americans more often prefer speaking in their native language even if they have lived in the United States."

When Helio LLC wanted to market a new $250 ultra-high-tech cellphone this year, it targeted three distinct groups: spoiled teens, tech geeks and Korean Americans.

Korean Americans make up less than 1 percent of the U.S. population, but U.S. telecommunications firms take note of them because their kin across the Pacific are among the most tech-savvy people on the planet.

Some Koreans who come to the United States find it's like going back in time a few years: They have to give up gadgets they're used to. So Helio decided to tap them as a unique market, a laboratory of sorts for germinating products they hope will catch on nationwide.
