Starting next week the television tastes of Latinos who watch Spanish language programming will begin to count, at least if you watch Univision.

Nielsen Media Research will include in its national ratings shows aired by Univision Communications Inc. Since 1992 a separate and unequal panel of estimation was used for Spanish language television programming. Telemundo, owned by NBC is expected to also be counted in the Nielson ratings. According to the LA Times:
Among the 18-to-34-year-old crowd, Univision frequently would finish second, behind Fox.
