This fall, ABC will become the first American network to make its primetime schedule available in Spanish, as part of an effort to draw in the country’s ever-expanding Hispanic population. The network will use a combination of voice-dubbing and closed captioning to translate its entire lineup of entertainment programs. Hispanics, the fastest-growing minority population in the U.S., make up 1/7 of the overall population, and studies have shown that a high percentage watch mainly Spanish-language channels, eschewing the programming offered by the larger broadcast networks.
