Don’t tell Arizona: Spanish-lingo net Univision just pulled off its first-ever week-long win among adults 18-49.

Granted, it was a low-viewership Labor Day holiday week. But it still reps a major milestone for Univision — and a reminder that demographics are indeed changing in this country.

Why the Univision surge? Beyond the holiday-fueled low viewership at the English nets, Univision notes that this past weekend featured a strong Fútbol Liga Mexicana (Mexico vs. Ecuador) soccer game on Saturday night and the finale of “Desafío: La Gran Batalla,” which “was a bit higher than its average Sunday night performance, despite airing on a holiday weekend.”

Univision was also up 27% year to year in the demo, thanks also to hot telenovelas “Hasta que el Dinero Nos Separe” (For Love or Money) and “Soy Tu Dueña” (Woman of Steel).

Here are some more Univision stats:
